Breast Cancer - Men can get it too!

Blog Adda featured this post on Breast Cancer in their Spicy Saturday Picks October 9, 2010


October is breast cancer awareness month and this post is specifically for the Online Breast Cancer Awareness Campaign

If you thought breast cancer was "for women only", think again. Although the incidence is more in women compared to men, men can also at risk.

What is breast cancer? 
Breast cancer is a malignant tumor that starts from breast cells. A malignant tumor is a group of cancer cells that may invade surrounding tissues or spread to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too.

What are the risk factors for breast cancer in men?


A risk factor is anything that affects your chance of getting a disease such as cancer. Different cancers have different risk factors. For example, exposing skin to strong sunlight is a risk factor for skin cancer. Smoking is a risk factor for cancers of the lung, mouth, larynx (voice box), bladder, kidney, and several other organs.

But risk factors don't tell us everything. Having a risk factor, or even several, does not mean that you will get the disease. Some men with one or more breast cancer risk factors never develop the disease, while most men with breast cancer have no apparent risk factors. Even when someone has a risk factor, there is no way to prove that it actually caused the cancer.

The causes of breast cancer in men is not yet fully understood, but research shows several factors that may increase the risk of getting it. As with female breast cancer, many of these factors are related to sex hormone levels in the body. Here they are
Aging

Aging is an important risk factor for the development of breast cancer in men. The risk of breast cancer goes up as a man ages. Men with breast cancer are on average about 68 years old when they are diagnosed.

Family history of breast cancer
Breast cancer risk is increased if other members of the family (blood relatives) have had breast cancer. About 1 out of 5 men with breast cancer have close male or female relatives with the disease.

Inherited gene mutations
A mutation or change in the BRCA2 gene, which is responsible for some breast cancers in women, probably accounts for about 1 in10 breast cancers in men. BRCA1 mutations can also cause breast cancer in men, but the risk is not as high as it is for mutations in the BRCA2 gene. People with these mutations typically have a strong family history of breast and/or ovarian cancer. Cancers in these families often occur in people younger (under 60) than the usual age.

Other mutations that may be responsible for some breast cancers in men include those in genes called CHEK2 and PTEN.

Klinefelter syndrome
This is a congenital condition that affects about 1 in 1,000 men. Normally the cells in men's bodies have a single X chromosome along with a Y chromosome, while women's cells have 2 X chromosomes. Men with this condition have cells with a Y chromosome plus at least 2 X chromosomes (sometimes as many as 4). Men with Klinefelter syndrome have small testicles (smaller than usual). Often, they are unable to produce functioning sperm cells, making them infertile. Compared with other men, they have lower levels of the male hormone androgens and more female hormones or estrogens. So they often develop gynecomastia or benign male breast growth.

Radiation exposure
A man whose chest area has been treated with radiation (such as for the treatment of a cancer in the chest, such as lymphoma) has an increased risk of developing breast cancer.

Alcohol
Heavy alcohol drinkers have an increased risk of breast cancerr. This may be because of its effects on the liver.

Liver disease
The liver plays an important role in sex hormone metabolism by making binding proteins that carry the hormones in the blood. These binding proteins affect the hormones' activity. Men with severe liver disease such as cirrhosis have relatively low levels of androgens and higher estrogen levels. Therefore, they may have an increased risk of developing breast cancer.

Estrogen treatment
Estrogen-related drugs are sometimes used in hormonal therapy for men with prostate cancer. This treatment may slightly increase their breast cancer risk. However, this risk is small compared with the benefits of this treatment in slowing the growth of prostate cancer. Men taking high doses of estrogens as part of a sex change procedure may also have a higher breast cancer risk.

Obesity
Recent studies have shown that women's breast cancer risk is increased by obesity during her adult life. Obesity is probably a risk factor for male breast cancer as well. The reason is that fat cells in the body convert male hormones into female hormones. This means that obese men have higher levels of estrogens in their body. Some obese men may notice that they don't have to shave as frequently as other men. They might also have trouble fathering children. Regular exercise and maintaining a healthy weight may help reduce the risk of breast cancer, as well as that of many other diseases and cancers.

Testicular conditions
Some studies have suggested that certain conditions that affect the testicles, such as having an undescended testicle, having mumps as an adult, or having one or both testicles surgically removed may increase breast cancer risk.

Certain occupations
There is an increased risk in men who work in hot environments such as steel mills. This could be because long-term exposure to higher temperature can affect the testicles, which in turn would affect hormone levels. Men heavily exposed to gasoline fumes may also have a higher risk. There is on-going research to know more about this.

Diagnosis is different in men. Men do not have to go through a mammogram
Instead, they go through physical examinations and a biopsy.
