Hello and welcome to this video on the morphology of benign and malignant tumors.
Tumors, also known as neoplasms, are abnormal growths of cells that can be either benign or malignant. Benign tumors are non-cancerous, while malignant tumors are cancerous and have the potential to spread to other parts of the body.
Let's first look at the morphology of benign tumors. Benign tumors are usually well-defined, with a clear border separating them from surrounding tissue. They are typically slow-growing and may be encapsulated, meaning that they are surrounded by a fibrous capsule. Benign tumors usually have a uniform appearance, with cells that closely resemble normal cells. They are usually localized and do not invade nearby tissues or spread to other parts of the body.
Now, let's look at the morphology of malignant tumors. Malignant tumors tend to have an irregular shape and an infiltrative growth pattern, meaning that they invade surrounding tissues. They may not be encapsulated, making it difficult to distinguish where the tumor ends and normal tissue begins. The cells in malignant tumors may appear abnormal and have varying shapes and sizes. They may also have a higher rate of mitosis, which is the process of cell division, compared to normal cells. Malignant tumors may also have a high degree of vascularity, meaning that they have a lot of blood vessels, which help to supply the tumor with nutrients.
In addition, malignant tumors can spread to other parts of the body through a process known as metastasis. This means that cancer cells from the primary tumor can break off and travel through the blood or lymphatic system to other parts of the body, where they can form secondary tumors
