What is male breast cancer?
It is thought that commonly breast cancer is a disease affecting only women, but men can also catch this cancer. In men However, cancer is much rarer than in women with only one in every 100,000 men affected.
Normal male breast
The normal male or female breast has:
Lobules (milk-producing packing gland)
Ducts (tiny tubes that route milk from lobules to fitting)
Stroma (fatty tissue and connective tissue surrounding ducts and lobules
Tiny blood vessels, and lymphatic vessels
Male breast Structure
Male breast lymphatic system.
Until puberty, young boys and girls have a little bit of breast tissue consist of a few ducts located underneath the fitting and areola (dark place around the fitting). At puberty, the female hormones in the girls make the breast ducts develop, lobules at the ends of the ducts, and form the amount of stroma to increase.
In boys, male hormones performed by the testicles maintain the breast tissue to grow as much as females. The tissue of the bosom of humans has ducts, but only a few if all lobules.
Causes of breast cancer
Some risk factors predispose to developing male breast cancer. The most important of these is age because most cases develop after 70 years. Those who are alcoholics or obese are also at a greater risk. The risk is high among patients who have a family member (male or female) with breast cancer.
In addition, men with the syndrome called a rare genetic condition Klinefelter are 20 to 50 times more likely to catch breast cancer than normal men. Men with Klinefelter syndrome have an extra, female, X chromosome, making them XXY, and often have slightly more breast tissue than normal.
The highest risk factors include radiation to the chest when the young person and exposure to hormonal treatment for the other disease revises. Men with high blood levels of female hormone estrogen are in danger of breast cancer.
How many people breast cancer affects?
In the UK around 300 new cases of breast cancer in men are diagnosed annually with majority patients on 60 to 70 years. In the United States, 2,190 men are expected to be diagnosed, and 410 are expected to die from disease in 2012.
Breast cancer regimes are slightly higher in Jewish men. This could because of genetic associations between breast cancer and some inherited genes.
Globally there are the highest regimes in Zambia. This could be due to common endemic liver infections there that lead to increased production of estrogen in men. Japan has a more limited incidence of breast cancer for men and women.
Sympt40mes of male breast cancer
Most common symptom of male breast cancer is developing a hard and painless piece more than one of the breasts or a free space or a bloodied flow of one of the fittings. The shape of the affected breast and the fitting may differ from the other. If the cancer has spread to the lymph nodes in the respective armpit, the glands there can be as well inflated.
Male and female breast cancer comparison
Similarities and differences in male and female breast cancer:
Most of the risk factors for breast cancer in men are also seen in women.
The signs and sympt40mes of the disease are the same in both sexes and reactions to the claim are assimilated.
The survival of breast cancer is assimilated in men and women
The same types of tumors seen in women are also seen in men
The average age of the diagnosis however is five to ten years later for men than for women.
The number of estrogen receptor containing breast tumors (positive estrogen receptor tumors) in men is higher than in women
Male breast cancer claims
Male breast cancer is treated primarily with surgery to remove part of the breast. Then chemotherapy and/or radiotherapy can be used to destroy residual cancer cells.
Chemotherapy and radiation therapy can only be used if the cancer is as well advanced and spread to other organs. Hormonal treatment with tamoxifen that helps to block the effects of hormones on the breast tissue that are known to stimulate the growth of cancer cells can be used to prevent cancer recurrence.
Outlook for male breast cancer
The results of treatment in male breast cancer are less favorable than for breast cancer in women. This is mainly because cancer often is found later and there is a lack of awareness of the condition.
However, those diagnosed in step 1 have a diet 75-100% of survival 5 years after diagnosis, those diagnosed in stages 2 or 3 have a diet 50-80% of the survival of five years and those diagnosed in stage 4 or advanced stages have a diet 30-60% of the surviving E five years.
