Breast cancer is caused by breast cancer cells that form into a lump or tumor.
Mutations in the breast cells cause them to become cancerous. These mutations could be caused by genetics, if a woman has a history of breast cancer in her family, or it could be caused by the hormonal imbalance in a woman's body during menopause.
These are the two most common causes of breast cancer, although there are others. Unfortunately, scientists are having a hard time figuring out what the other causes of breast cancer are.
Although finding a lump in the breast can be a very scary experience for women, not all lumps are cancerous. Any lump or unusual characteristic should be reported to and examined by a doctor to see if it is cancerous.
Many lumps are benign, which means that they are not dangerous and not spreading.
If a lump is cancerous then it is known as malignant, which means that it has the capability of spreading throughout the body if it is not removed.
Lumps of breast cancer cells usually form in the milk glands of the breast. These cancerous cells continue to grow and then move into the breast tissue and spread into the lymph nodes under the arms. This occurs in stages two and three.
After the cancer spreads to the lymph nodes, it will continue to spread throughout the body, which is called stage four breast cancer. Common places for it to spread are the bones, liver, and lungs.
Cancerous cells that spread throughout the body can be very hard to treat. Chemotherapy is the most common treatment for breast cancer and focuses on killing the cancerous cells before they can spread any further. Unfortunately, killing all of the cancer can be very hard to do if it has already spread throughout the body.
On the other hand, if the cancer is discovered early, it is much easier to treat. Cancerous cells that are still contained in the breast can be removed fairly easily by surgery.
Chemotherapy is still usually done after surgery to kill any remaining breast cancer cells, but the treatments are taken for a much shorter time than if the cancer could not have been surgically removed.
Note that that there are also more natural, healthier ways to treat breast cancer.
