Oncology.

Oncology is a branch of medicine that specializes in the diagnosis and treatment of cancer. It includes medical oncology (the use of chemotherapy, hormone therapy, and other drugs to treat cancer),

radiation oncology (the use of radiation therapy to treat cancer), and surgical oncology (the use of surgery and other procedures to treat cancer).

Breast Cancer

is a disease in which cells in the breast grow out of control. It is the most common cancer diagnosed in women, but men can get breast cancer, too. Breast cancer is classified depending on which cells in the breast turn into cancer, whether they produce hormones, and which genetic changes they show. Treatment is based on the type of breast cancer and its stage. Other factors, including overall health, menopause status, and personal preferences, are also considered.

Brain Tumor A brain tumor is the growth of abnormal cells in the brain. There are over 120 types of brain tumors. Not all brain tumors are brain cancer, but even benign tumors can be dangerous because of their size or location.

Colorectal Cancer Colorectal cancer starts in the large intestine (colon) or the rectum (end of the colon). These cancers can also be called colon cancer or rectal cancer, depending on where they start. They are often grouped together because they have many features in common.

Lung Cancer

is cancer that forms in the tissues of the lung, usually in the cells that line the air passages. It is the leading cause of cancer death in both men and women. There are two main types: small-cell lung cancer and non-small-cell lung cancer. Smoking causes most lung cancers, but nonsmokers can also develop lung cancer.

Ovarian Cancer

is an umbrella term for a multitude of different types of cancer that affect not only the ovaries, but also other parts of the female reproductive system. The symptoms of ovarian cancer are vague and sometimes confused with other, less serious illnesses. With the delay in diagnosis, advanced cancer becomes more difficult to treat. Therefore, taken together, ovarian cancer is the most lethal of the female cancers.

Prostate Cancer

is the most common cancer and the second leading cause of cancer death among men. While aggressive types of prostate cancer may worsen and spread quickly in some patients, in most men, prostate cancer usually grows very slowly. Finding and treating it before symptoms occur may not improve men’s health or help them live longer. Therefore, patients with slow-growing tumors confined to the prostate gland may consider “active surveillance” instead of surgery or radiation treatment.
