Cancer

Cancer is the catchall term applied to diseases caused by the uncontrolled growth of abnormal cells. Cancer isn't one disease. It is many different diseases, more than 100 and counting.

Each kind of cancer is usually named for the cell type in which it begins — cancer that starts in a lung is called lung cancer; cancer that starts in pigment cells in the skin, which are known as melanocytes, is called melanoma.

When detected and treated early, cancer can often be stopped. That said, cancer is a leading cause of death and disability around the world.

Bone Marrow Transplant

A bone marrow transplant is a procedure used to treat certain types of cancer and some other diseases. Before the bone marrow transplant takes place, a person's bone marrow cells are destroyed with radiation or chemotherapy. The cells that normally live in the bone marrow and that are responsible for making blood cells are then replaced. Bone marrow cells are blood cells that are located in the spongy center of bones. These include: Cells to replace your original cells can be taken from your blood or bone marrow before the procedure starts. Bone marrow cells also can be taken from a different person (a donor) whose cells are a good match for the person receiving the transplant (the recipient). A good match means certain chemical markers on the cells of both donor and recipient are as close as possible and thus minimizes the possibility that the cells will be rejected by your body.

Chemotherapy

Chemotherapy drugs kill cancer cells or prevent them from growing and dividing. Chemotherapy drugs are also called anti-cancer drugs. Chemotherapy drugs can shrink or limit the size of cancerous tumors. They may also prevent cancer from spreading to other parts of the body. There are more than 80 anti-cancer drugs. Cancer treatment often requires a combination of two or more different drugs. Cancer specialists design chemotherapy plans based on the cancer being treated and how far the cancer has spread.

Stereotactic Biopsy of the Breast

Stereotactic biopsy of the breast is a special type of large core needle biopsy. It is one method of guiding the biopsy needle to the desired location in the breast. Core needle biopsy can also be guided by ultrasound or by the standard x-ray techniques used in mammography. Large core needle biopsy is often the diagnostic method of choice to evaluate abnormalities that are visible on a mammogram but cannot easily be felt by hand. Core needle biopsy may not be suitable for women who have: In these situations, accurate results from a core needle biopsy may not be possible. Instead, your doctor may recommend a surgical biopsy.

Stay ahead of skin cancer

About 58 million people have at least one actinic keratosis (AK), a precancerous skin growth caused by too much sun exposure. Yet, most people don’t see the potential danger of these lesions because they are small, with few if any annoying symptoms, and can go away almost as fast as they appear. Still, people need to watch out for AKs and get the appropriate treatment from a dermatologist because if left alone, they can turn into squamous cell skin cancer, the second most common type of skin cancer.
