How is breast cancer treated and diagnosed . 

You or someone you care about may have recently been diagnosed with breast cancer. Breast cancer is a disease in which certain cells in the breast develop uncontrollably.. Breast cancer treatments can include surgery, radiotherapy, chemotherapy, hormonal therapy, targeted therapy, and immunotherapy. There are some types of surgery, depending on the size and location of the tumor.

How is the tumor removed from the body.

During a lumpectomy, the tumor is removed along with the affected tissue and a little of the normal surrounding it. In a complete or simple affected mastectomy, during a modified radical mastectomy, the entire breast is removed. Some lymph nodes under the arm are removed and sometimes other tissue in the chest is cut.

When does a doctor give radiotherapy to a patient with breast cancer.

This radiation therapy is used to kill cancer cells or stop them from growing and multiplying. An external beam uses a machine outside the body that directs radiation toward the cancer. This uses internal radiation therapy, also known as brachytherapy, which is a substance that emits radiation through different types of device insertion. The material is placed inside the breast where all of the cancer has been removed.

How is chemotherapy used to treat breast cancer.

Chemotherapy uses certain drugs to kill cancer. The drugs can treat cancer cells throughout the body, or they can be given to treat cancer cells in one area. Another treatment option is hormone therapy. Hormones are natural substances in your body. Estrogen is one of the hormones present. The body uses estrogen primarily to promote and develop the uterus, breasts, and ovaries. However, estrogen can promote the growth of some hormone-positive cancer cells.. One type of hormone therapy prevents estrogen from binding to breast cancer cells so it doesn't cause cancer cells to grow and divide.

How is targeted therapy for cancer cells.

Cancer-targeted therapy is a treatment option for cancers that have a specific type of marker on the cancer cells. One treatment classifies cancer cells with a marker called HER2. HER2 is a protein naturally found in cells that promotes healthy growth in the body's cells. Some cancer cells contain a lot of this protein. This helps cancer cells to grow and spread more aggressively than normal cells.. As a result, cancer cells stop growing and may die. Immuno-oncology, also known as immunotherapy, helps the immune system fight cancer. Cancer often hides from immune cells that attack it.. For example, both cancer cells and the immune system may contain proteins called checkpoint proteins. Upon attachment, the attack of other immune cells stops.

Scientists are looking at one type of immunotherapy drug that prevents checkpoint proteins from binding to each other and, eventually, the immune cell can attack and destroy the cancer cell. Your doctor may prescribe a combination of different treatments or treatment options. If you have questions about breast cancer or something to see right away, talk to your doctor. Most importantly, take your medications as directed and report any side effects you have.
