Some forms of cancer can be completely cured with drugs alone. Many different chemo medicines are available. You will probably need frequent blood tests to determine how your body is doing and how much chemo you need. The drugs can produce many side effects, and may leave you susceptible to infection for a while. Natural hormones such as estrogen sometimes promote the growth of cancer cells.
Special drugs are available to block the estrogen and slow the cancerous growth.
In most cases, you can take this medicine by mouth. In some cases, it may also be necessary to surgically remove sources of estrogen such as the ovaries or adrenal glands. They can also be effective in reducing pain, controlling bleeding, and shrinking cancerous tumors. Doctors also use this type of therapy on cancerous lymph nodes. Radiation and chemotherapy are often used together.
