                    Chronic lymphocytic leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell).
                    Chronic lymphocytic leukemia (also called CLL) is a blood and bone marrow disease that usually gets worse slowly. CLL is one of the most common types of leukemia in adults. It often occurs during or after middle age; it rarely occurs in children.
                
                
                    Leukemia may affect red blood cells, white blood cells, and platelets.
                    Normally, the body makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell.   A myeloid stem cell becomes one of three types of mature blood cells:         -  Red blood cells that carry oxygen and other substances to all tissues of the body.    -  White blood cells that fight infection and disease.     -  Platelets that form blood clots to stop bleeding.        A lymphoid stem cell becomes a lymphoblast cell and then one of three types of lymphocytes (white blood cells):         -  B lymphocytes that make antibodies to help fight infection.    -  T lymphocytes that help B lymphocytes make antibodies to fight infection.    -  Natural killer cells that attack cancer cells and viruses.         In CLL, too many blood stem cells become abnormal lymphocytes and do not become healthy white blood cells. The abnormal lymphocytes may also be called leukemia cells. The lymphocytes are not able to fight infection very well. Also, as the number of lymphocytes increases in the blood and bone marrow, there is less room for healthy white blood cells, red blood cells, and platelets. This may cause infection, anemia, and easy bleeding.    This summary is about chronic lymphocytic leukemia. See the following PDQ summaries for more information about leukemia:          -  Adult Acute Lymphoblastic Leukemia Treatment.    -  Childhood Acute Lymphoblastic Leukemia Treatment.    -  Adult Acute Myeloid Leukemia Treatment.    -  Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment.    -  Chronic Myelogenous Leukemia Treatment.    -  Hairy Cell Leukemia Treatment.
Older age can affect the risk of developing chronic lymphocytic leukemia. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for CLL include the following:         - Being middle-aged or older, male, or white.    - A family history of CLL or cancer of the lymph system.    - Having relatives who are Russian Jews or Eastern European Jews.
Signs and symptoms of chronic lymphocytic leukemia include swollen lymph nodes and tiredness. Usually CLL does not cause any signs or symptoms and is found during a routine blood test. Signs and symptoms may be caused by CLL or by other conditions. Check with your doctor if you have any of the following:         - Painless swelling of the lymph nodes in the neck, underarm, stomach, or groin.    - Feeling very tired.    - Pain or fullness below the ribs.    -  Fever and infection.    - Weight loss for no known reason.
Tests that examine the blood, bone marrow, and lymph nodes are used to detect (find) and diagnose chronic lymphocytic leukemia. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.     -   Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following:                -  The number of red blood cells and platelets.      - The number and type of white blood cells.      - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.      - The portion of the blood sample made up of red blood cells.              -   Immunophenotyping : A laboratory test in which the antigens or markers on the surface of a blood or bone marrow cell are checked to see if they are lymphocytes or myeloid cells. If the cells are malignant lymphocytes (cancer), they are checked to see if they are B lymphocytes or T lymphocytes.    -   FISH (fluorescence in situ hybridization): A laboratory technique used to look at genes or chromosomes in cells and tissues. Pieces of DNA that contain a fluorescent dye are made in the laboratory and added to cells or tissues on a glass slide. When these pieces of DNA bind to specific genes or areas of chromosomes on the slide, they light up when viewed under a microscope with a special light.     -   Flow cytometry : A laboratory test that measures the number of cells in a sample, the percentage of live cells in a sample, and certain characteristics of cells, such as size, shape, and the presence of tumor markers on the cell surface. The cells are stained with a light-sensitive dye, placed in a fluid, and passed in a stream before a laser or other type of light. The measurements are based on how the light-sensitive dye reacts to the light.    -   IgVH gene mutation test: A laboratory test done on a bone marrow or blood sample to check for an IgVH gene mutation. Patients with an IgVH gene mutation have a better prognosis.    -   Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for abnormal cells.
Certain factors affect treatment options and prognosis (chance of recovery). Treatment options depend on:         - The stage of the disease.    - Red blood cell, white blood cell, and platelet blood counts.    - Whether there are signs or symptoms, such as fever, chills, or weight loss.    - Whether the liver, spleen, or lymph nodes are larger than normal.    - The response to initial treatment.    - Whether the CLL has recurred (come back).        The prognosis (chance of recovery) depends on:         - Whether there is a change in the DNA and the type of change, if there is one.    - Whether lymphocytes are spread throughout the bone marrow.    - The stage of the disease.    - Whether the CLL gets better with treatment or has recurred (come back).    - Whether the CLL progresses to lymphoma or prolymphocytic leukemia.    - The patient's general health.

In myeloproliferative neoplasms, too many blood stem cells become one or more types of blood cells. The neoplasms usually get worse slowly as the number of extra blood cells increases.
                
                
                    There are 6 types of chronic myeloproliferative neoplasms.
                    The type of myeloproliferative neoplasm is based on whether too many red blood cells, white blood cells, or platelets are being made. Sometimes the body will make too many of more than one type of blood cell, but usually one type of blood cell is affected more than the others are. Chronic myeloproliferative neoplasms include the following 6 types:         -  Chronic myelogenous leukemia.    -  Polycythemia vera.    -  Primary myelofibrosis (also called chronic idiopathic myelofibrosis).     -  Essential thrombocythemia.    -  Chronic neutrophilic leukemia.    -  Chronic eosinophilic leukemia.        These types are described below. Chronic myeloproliferative neoplasms sometimes become acute leukemia, in which too many abnormal white blood cells are made.
Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myeloproliferative neoplasms. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual.

An unusual (higher or lower than normal) amount of a substance can be a sign of disease.    -   Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for abnormal cells.    -   Cytogenetic analysis : A test in which cells in a sample of blood or bone marrow are viewed under a microscope to look for certain changes in the chromosomes. Certain diseases or disorders may be diagnosed or ruled out based on the chromosomal changes.    -   Gene mutation test: A laboratory test done on a bone marrow or blood sample to check for mutations in  JAK2 ,  MPL , or  CALR genes. A JAK2 gene mutation is often found in patients with polycythemia vera, essential thrombocythemia, or primary myelofibrosis. MPL or CALR gene mutations are found in patients with essential thrombocythemia or primary myelofibrosis.

                    There is no standard staging system for chronic myeloproliferative neoplasms.
                    Staging is the process used to find out how far the cancer has spread. There is no standard staging system for chronic myeloproliferative neoplasms. Treatment is based on the type of myeloproliferative neoplasm the patient has. It is important to know the type in order to plan treatment.

                    Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin.
                    The skin is the body's largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin D. The skin has several layers, but the two main layers are the epidermis (top or outer layer) and the dermis (lower or inner layer). Skin cancer begins in the epidermis, which is made up of three kinds of cells:         -  Squamous cells: Thin, flat cells that form the top layer of the epidermis. Cancer that forms in squamous cells is called squamous cell carcinoma.    -  Basal cells: Round cells under the squamous cells. Cancer that forms in basal cells is called basal cell carcinoma.    -  Melanocytes: Found in the lower part of the epidermis, these cells make melanin, the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to tan, or darken. Cancer that forms in melanocytes is called melanoma.
                
                
                    Nonmelanoma skin cancer is the most common cancer in the United States.
                    Basal cell carcinoma and squamous cell carcinoma are also called nonmelanoma skin cancer and are the most common forms of skin cancer. Most basal cell and squamous cell skin cancers can be cured.    Melanoma is more likely to spread to nearby tissues and other parts of the body and can be harder to cure. Melanoma is easier to cure if the tumor is found before it spreads to the dermis (inner layer of skin). Melanoma is less likely to cause death when it is found and treated early.    In the United States, the number of cases of nonmelanoma skin cancer seems to have increased in recent years. The number of cases of melanoma has increased over the last 30 years. Part of the reason for these increases may be that people are more aware of skin cancer. They are more likely to have skin exams and biopsies and to be diagnosed with skin cancer.   Over the past 20 years, the number of deaths from melanoma has decreased slightly among white men and women younger than 50 years. During that time, the number of deaths from melanoma has increased slightly among white men older than 50 years and stayed about the same among white women older than 50 years.   The number of cases of childhood melanoma diagnosed in the United States is low, but increasing over time. The number of childhood deaths from melanoma has stayed about the same.

Being exposed to ultraviolet radiation may increase the risk of skin cancer. Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor.    Being exposed to ultraviolet (UV) radiation and having skin that is sensitive to UV radiation are risk factors for skin cancer. UV radiation is the name for the invisible rays that are part of the energy that comes from the sun. Sunlamps and tanning beds also give off UV radiation.   Risk factors for nonmelanoma and melanoma cancers are not the same.         -  Nonmelanoma skin cancer risk factors include:               - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time.      - Having a fair complexion, which includes the following:                        - Fair skin that freckles and burns easily, does not tan, or tans poorly.         - Blue or green or other light-colored eyes.          - Red or blond hair.                      - Having actinic keratosis.       - Past treatment with radiation.      - Having a weakened immune system.       - Being exposed to arsenic.             -  Melanoma skin cancer risk factors include:               - Having a fair complexion, which includes the following:                         - Fair skin that freckles and burns easily, does not tan, or tans poorly.          - Blue or green or other light-colored eyes.          - Red or blond hair.                     - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time.       - Having a history of many blistering sunburns, especially as a child or teenager.       - Having several large or many small moles.      - Having a family history of unusual moles (atypical nevus syndrome).      -  Having a family or personal history of melanoma.       - Being white.

                    - Myelodysplastic/myeloproliferative neoplasm, unclassifiable, is a disease that has features of both myelodysplastic and myeloproliferative diseases but is not chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, or atypical chronic myelogenous leukemia.    - Signs and symptoms of myelodysplastic/myeloproliferative neoplasm, unclassifiable, include fever, weight loss, and feeling very tired.
                
                
                    Myelodysplastic/myeloproliferative neoplasm, unclassifiable, is a disease that has features of both myelodysplastic and myeloproliferative diseases but is not chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, or atypical chronic myelogenous leukemia.
                    In myelodysplastic /myeloproliferative neoplasm, unclassifiable (MDS/MPD-UC), the body tells too many blood stem cells to become red blood cells, white blood cells, or platelets. Some of these blood stem cells never become mature blood cells. These immature blood cells are called blasts. Over time, the abnormal blood cells and blasts in the bone marrow crowd out the healthy red blood cells, white blood cells, and platelets.   MDS/MPN-UC is a very rare disease. Because it is so rare, the factors that affect risk and prognosis are not known.
Signs and symptoms of myelodysplastic/myeloproliferative neoplasm, unclassifiable, include fever, weight loss, and feeling very tired. These and other signs and symptoms may be caused by MDS/MPN-UC or by other conditions. Check with your doctor if you have any of the following:         -  Fever or frequent infections.    - Shortness of breath.    - Feeling very tired and weak.    - Pale skin.    - Easy bruising or bleeding.    -  Petechiae (flat, pinpoint spots under the skin caused by bleeding).    - Pain or a feeling of fullness below the ribs.
Because myelodysplastic /myeloproliferative neoplasm, unclassifiable (MDS/MPN-UC) is a rare disease, little is known about its treatment. Treatment may include the following:         -  Supportive care treatments to manage problems caused by the disease such as infection, bleeding, and anemia.     -  Targeted therapy (imatinib mesylate).        Check the list of NCI-supported cancer clinical trials that are now accepting patients with myelodysplastic/myeloproliferative neoplasm, unclassifiable. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.

                    Penile cancer is a disease in which malignant (cancer) cells form in the tissues of the penis.
                    The penis is a rod-shaped male reproductive organ that passes sperm and urine from the body. It contains two types of erectile tissue (spongy tissue with blood vessels that fill with blood to make an erection):          - Corpora cavernosa: The two columns of erectile tissue that form most of the penis.    -  Corpus spongiosum: The single column of erectile tissue that forms a small portion of the penis. The corpus spongiosum surrounds the urethra (the tube through which urine and sperm pass from the body).        The erectile tissue is wrapped in connective tissue and covered with skin. The glans (head of the penis) is covered with loose skin called the foreskin.
Human papillomavirus infection may increase the risk of developing penile cancer. Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for penile cancer include the following:    Circumcision may help prevent infection with the human papillomavirus (HPV). A circumcision is an operation in which the doctor removes part or all of the foreskin from the penis. Many boys are circumcised shortly after birth. Men who were not circumcised at birth may have a higher risk of developing penile cancer.    Other risk factors for penile cancer include the following:         - Being age 60 or older.    - Having phimosis (a condition in which the foreskin of the penis cannot be pulled back over the glans).    - Having poor personal hygiene.    - Having many sexual partners.    - Using tobacco products.
Tests that examine the penis are used to detect (find) and diagnose penile cancer. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking the penis for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.    -   Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue sample is removed during one of the following procedures:                -  Fine-needle aspiration (FNA) biopsy : The removal of tissue or fluid using a thin needle.      -  Incisional biopsy : The removal of part of a lump or a sample of tissue that doesn't look normal.      -  Excisional biopsy : The removal of an entire lump or area of tissue that doesnt look normal.
