SURGERY
Wide Local Excision (Breast Conserving Surgery Procedure)
This operation saves as much of your breast as possible by removing only the lump plus a surrounding area of normal tissue. Many women can have this treatment-often followed by radiation therapy-instead of mastectomy, and in most cases survival rates for both operations are similar. But this treatment may not be an option if:
If you have a large tumor but still want to consider the possibility of this treatment, chemotherapy before surgery may be an option to shrink the tumor and make you eligible for the procedure.
After surgery, your breasts may not match in size and shape. This is because removing breast tissue during surgery usually makes the affected breast appear smaller; however, swelling in response to surgery may also make your breast appear bigger (not a permanent effect).
Mastectomy
Mastectomy involves removal of all of the breast tissue, sometimes along with other nearby tissues. Mastectomy may be right for you if:
The effect and risk of this treatment are:
If you are having a mastectomy, your doctor will discuss more about breast reconstruction with you. Breast reconstruction is surgery to rebuild your breast shape. It cannot give a woman back her breast - a reconstructed breast does not have natural sensations. However, the surgery offers a result that looks like a breast. Breast reconstruction may take more than one surgery. Extra steps may include:
Axillary Lymph Nodes Dissection
A traditional axillary lymph node dissection usually removes nodes in levels I and II. For women with invasive breast cancer, this procedure accompanies a mastectomy or breast conserving surgery. It may be done at the same time as, or after, a lumpectomy (through a separate incision).
Based on the doctor's physical exam and other indicators about the likelihood that cancer has spread to your lymph nodes, the surgeon will generally remove between five and thirty nodes during a traditional axillary dissection. The total number of lymph nodes "involved" (showing evidence of cancer) is more important than the extent of cancer in any one node.
Your doctor will let you know if any lymph nodes were involved (and if so, how many), as well as the extent of tumor involvement in each nodes.
There are center which may offer sentinel nodes biopsy as alternative to axillary lymph nodes dissection however the surgery only offered for certain cases only.
THERAPY
CHEMOTHERAPY
Chemotherapy is the use of cancer-killing drugs injected into a vein, given as a shot, or taken as a pill or liquid. These drugs enter the bloodstream and go throughout the body, making the treatment useful for cancers that have spread to distant organs. While these drugs kill cancer cells, they also damage some normal cells, which can lead to side effects.
The most common side effects of chemotherapy:
Three different chemotherapy strategies may be used:
Ports for Chemo
Your oncologist may recommend that you have a port or "port-a-cath" inserted in your upper chest wall (the space between your collarbone and your breast) to make chemotherapy easier and more comfortable for you. You will have a chest X-ray to confirm that the port is positioned correctly. When chemotherapy is over, the port can be removed quickly in another same-day procedure. The port is about the size of a quarter, only thicker, and will show only as a bump underneath the skin.
There are several benefits to having a port:
RADIOTHERAPY
Radiation therapy is used to kill tumor cells if there are any left after surgery. It is a local treatment and therefore works only on tumor cells that are directly in its beam. It is used most often in people who have undergone conservative surgery such as lumpectomy. Conservative surgery is designed to leave as much of the breast tissue in place as possible. Radiation therapy is usually given five days a week over five to six weeks. Each treatment takes only a few minutes. It is painless and has relatively few side effects.
Side Effects of radiotherapy:
Most radiation side effects are temporary.
HORMONAL THERAPY
Hormone therapy is often used to treat women whose cancers are sensitive to hormones estrogen and progesterone receptor positive cancers. Similar to chemotherapy, this form of therapy can be used to decrease the chance of your cancer returning. If the cancer has already spread, hormone therapy may shrink and control it.
Two classes of medications are used in hormone therapy:
Selective Estrogen Receptor Modulators (SERMs)
SERMs act by:
SERMs can be used in both pre- and postmenopausal women. The most common SERM prescribed for hormone therapy is tamoxifen (Nolvadex). Tamoxifen is used to reduce the risk of breast cancer for women who:
You take tamoxifen daily, in pill form, for up to five years. It may reduce the risk of recurrence of breast cancer and is less toxic than most anti-cancer drugs. But tamoxifen isn't trouble-free. Women taking tamoxifen may experience menopausal symptoms such as:
More serious side effects including blood clots and endometrial cancer occur infrequently. Older women, especially those with other medical conditions, may be at greater risk of more serious side effects than are younger women.
Aromatase inhibitors
This class of drugs, which includes:
It blocks the conversion of a hormonal substance (androstenedione) into estrogen. This effectively stops estrogen production in cells other than the ovaries. Fat cells, the adrenal gland and other normal cells all make small amounts of estrogen.
These drugs are only effective in postmenopausal women.
