I have been doing research on cancer on many ways and for many years.

I have found out that for cancer breast reoval doctors usually prefer surgery.

On the the free site breastcancer.org the various ways of cancer breast removal are reported as following

Lumpectomy, also known as breast-conserving surgery, is the removal of only the tumor and a small amount of surrounding tissue.
Mastectomy is the removal of all of the breast tissue. Mastectomy is more refined and less intrusive than it used to be because in most cases, the muscles under the breast are no longer removed.
Lymph node removal, or axillary lymph node dissection, can take place during lumpectomy and mastectomy if the biopsy shows that breast cancer has spread outside the milk duct. Some people qualify for the less-invasive sentinel lymph node dissection.
Breast reconstruction is the rebuilding of the breast after mastectomy and sometimes lumpectomy. Reconstruction can take place at the same time as cancer-removing surgery, or months to years later. Some women decide not to have reconstruction and opt for a prosthesis instead.

Prophylactic mastectomy is preventive removal of the breast to lower the risk of breast cancer in high-risk people.
Prophylactic ovary removal is a preventive surgery that lowers the amount of estrogen in the body, making it harder for estrogen to stimulate the development of breast cancer.
Cryotherapy, also called cryosurgery, uses extreme cold to freeze and kill cancer cells. Right now, cryotherapy is an experimental treatment for breast cancer.

There is always hope, remember.
