Only 5 percent to 10 percent of breast cancer is owing to abnormal genes. The two genes, Breast Cancer Gene 1 (BRCA 1) and Breast Cancer Gene 2 (BRCA2) are thought to be those that increase the risk of breast cancer. However, the percentage of breast cancer cases in relation to BRCA1 and BRCA2 mutated genes is only 5%. It must be noted that this is only one of the risk factors when considering breast cancer. The other risk factors being age, high fat content diet and obesity, to name a few.

Myth: Radiation therapy causes a person to be radioactive.

Only in certain instances do you become radioactive when you receive radiation internally as a "boost". This is because the radioactive material is within you but while you receive this treatment, you generally will be in a private room in the hospital. If you receive radiation therapy externally this in no way makes you radioactive.

Myth: In early breast cancer detection, mammography is 100% accurate.

Nearly 85 to 90 percent of all breast cancers are detected by mammography, but a small percentage of breast cancers do go undetected by mammography. These go undetected sometimes because the irregular tissue and the surrounding breast tissue are of the same density. Therefore, if a patient has a lump in her breast or has any other change in her breast and also the mammogram gives a negative reading it is always best to continue to pursue the matter.

Myth: It is not necessary for women who are older and diagnosed with breast cancer to undergo "full" treatment.

The mortality rate of older women who have breast cancer is on the increase because of the fact that they do not receive the full treatment at the time they are diagnosed. Even though breast cancer is supposed to have a slow growth rate, some can be aggressive and can spread to other parts of the body.

Myth: Breast self-examination is best practiced in the shower.

It may be carried out in the shower, but it may not be the best of places to so as wet soapy hands may make it difficult to judge properly any abnormalities. Cold water or air too may cause the breasts and the nipples to contract. Breast self examination should be carried out monthly in three positions, that is standing up, lying down and upright in front of the mirror.

Myth: A woman's risk of developing breast cancer is increased by fibrocystic change.

Fibrocystic change is a breast condition, which is non-cancerous and has no risk whatsoever of increasing breast cancer. In some cases, however, this condition can cause detection with mammography a bit difficult because in fibrocystic breasts the breast density may tend to eclipse the breast cancer on a mammogram. It is therefore very important that breast self-examination as well as clinical breast examination is carried out. If cancer is suspected in these conditions, an ultra sound scan is also carried out.

Myth: A woman will definitely develop breast cancer if she is diagnosed with Lobular Carcinoma in situ.

Lobular Carcinoma in situ or lobular neoplasm is a stage 0 cancer, which most doctors do not consider to be a cancer. However, it might be an indication that an individual is at high risk and women with lobular neoplasm are more likely to develop breast cancer later on in their lives.
