Breast Cancer
Treatment
Women are
recommended to examine their breasts once in a month to detect any changes or
lumps. If breast self -examination detects a lump, the family doctor
should be consulted. In choosing therapy, the physician takes
into consideration the stage of the disease, the woman's age and menopausal
status. Breast cancer is usually treated surgically along with
chemotherapy, radio therapy and hormone therapy. Radio therapy kills
cancer cells using gamma radiation. Chemotherapy may use Cytotoxic drugs to
kill cancer cells both in the breast and elsewhere in the body. Modern
treatments have greatly improved the quality and quantity of life for
breast cancer patients.
Surgery
Surgery is the first line of
attack against breast cancer. There are two main type of surgeries for breast
cancer
Lumpectomy (Breast-conserving surgery)
: Any form of surgery that removes only part of the breast is considered
"breast-conserving" or "breast preservation" surgery.
Lumpectomy is the most common surgery used for best cancer today. It is used for
patients with early stage invasive breast cancers. A part of the
breast which contains the tumor and some normal tissues that surrounds the
tumor is removed during the surgery. Usually women with tumors 5 cm (2
inches) or less in diameter with positive or negative axillary lymph nodes, are
gone under this treatment. After the surgery, the patient may receive five
to seven weeks of radiotherapy in order to eliminate any cancer cells that may
be present in the remaining breast tissue.
Mastectomy : A method of surgery which involves
the removal of the breast cancer and a larger portion of the normal breast
tissue around the breast cancer or entire breast. Breast cancer surgery is
done under general anesthesia and usually takes two to three hours. The surgeon may also
remove the lining
over the chest muscles below the tumor and some lymph nodes under the arm. Women
who undergo a mastectomy have the option of breast reconstruction.
Side effects include, wound infection, hematoma (accumulation of blood in the
wound), and seroma (accumulation of clear fluid in the wound).
Chemotherapy
It is a combination of drugs which is effective to
kill or slow the growth of rapidly multiplying cells. The drugs are given
directly to vein or orally. The drug will travel to entire body through blood
stream and will destroy the cancer cells beyond the breast. Chemotherapy
is given in cycles of treatment followed by a recovery period. The entire
chemotherapy treatment generally lasts three to six months, depending on the
type of drugs given. When breast cancer is limited to the breast or lymph nodes, chemotherapy may
be given after a lumpectomy or mastectomy. This is known as adjuvant treatment
and may help reduce the chance of breast cancer recurrence.
The side effects will depend up on the type and amount of drugs you are
given. The side effects include
- Nausea and vomiting
- Loss of appetite
- Hair loss
- Mouth sores
- Changes in menstrual cycle
- Higher risk of infection (due to decreased white blood cells)
- Bruising or bleeding
- Fatigue
Radiation Therapy
Radiotherapy is a highly effective
treatment option which uses high levels of radiation to kill cancer cells or
keep them from growing and dividing thus reducing damage to healthy cells. It is usually given
to the breast to destroy cancer cells that may remain in
your breast after breast conserving surgery, or in any breast tissue left on
your chest after mastectomy. Having radiotherapy after surgery reduces the
chance that reoccurrence in the same place in the next 10 years. Radiation
therapy is usually delayed until chemotherapy is complete. Early side effects of
radiotherapy include skin reactions, tiredness and breast tenderness. These are
usually mild and pass after a few weeks. Radiation therapy is not
given during pregnancy because it can harm a fetus.
Two main types of
radiotherapy are used to treat breast cancer: External Radiotherapy and Internal
Radiotherapy
External Radio therapy : This is the usual method of radio therapy.
In this therapy, radiation is focused from a source outside the body on the area affected by
the cancer. Patients need to face the therapy at least six to eight weeks continuously.
Deodorants and antiperspirants can interfere with external beam radiation
therapy of the underarm area, so you should avoid using them until treatments
are complete. In some women, the breast becomes smaller and firmer after radiation therapy.
Internal Radio Therapy ( Brachytherapy ) : This
is a method of placing radioactive seeds directly into the breast tissue next to
the cancer. The radiation is sealed in needles, seeds, wires, or catheters. This
type of radiation has the advantage of delivering the radiation from a close
distance, and thereby deliver a higher dose of radiation while not causing as
much damage to other structures. Some of the radioactive substances used for
internal radiation treatment include cesium, iridium, iodine, phosphorus, and
palladium. The side effects of implant therapy depend on the area being treated.
