    The observations of male breast cancer over female breast cancer isn't very high in number because of the higher number of females getting breast cancer over males. This limits the understanding of the pathogenesis for male breast cancer. Its a mystery about whether or not biological behavior and tumor progression associated with male breast cancer are the same as that of the female form. The latest news on male breast cancer is that in a new study from the American Journal of Nursing, a researcher interviewed 28 men about breast cancer and all of the men had at least one relative on their mother's side who had breast cancer. This put these men in higher risks of getting breast cancer. 79% of these men didn't even know that men could get breast cancer! Even with their high risk, none of their health care providers had discussed the issue of getting breast cancer with them. Factors that raise the risk of men getting breast cancer who have a family history of breast cancer according to the American Cancer Society are old age, heavy alcohol consumption, and overweight.

    The rate of breast cancer in men compared to that of females is about 100 times more common in females than in men.

    The latest large new on breast cancer in men is that their is an association between type 2 diabetes mellitus and colorectal cancer in men but not in woman.

    Breast cancer although common in women it also occurs to men which is usually uncommon or rare. In the year 2001 around 1,500 men were diagnosed with breast cancer yet this is small compared to the 192,200 women that were diagnosed that year. Also only about 400 men died from the disease while 40,200 women died of the disease that year. The latest large news of breast cancer in men is since men have breast tissue behind the nipple (less developed than women) it means that men too get the cancer unlike the common belief that breast cancer is a girls cancer. Also getting the cancer is more scarring for men since the disease is rarer in them.

  4. Male breast cancer:

    Fraction of US population: 1 in 27400, about 0.0036%

    Number of US patients: 6530 per year

    Average patient age: 63


    Female Breast Cancer:

    Fraction of US population: 1 in 184, about 0.54%

    Number of US patients: 1.342 million per year

    Average patient age: 63


    Most men don't know that breast cancer can affect them too. Even when symptoms are discovered, men often wait to report the symptoms of male breast cancer leaving many men with less hope that treatment will lead to recovery. The survival rate for men is lower than for women. A cause of this may be because men are not taught to do regular breast self-examination. Symptoms include a painless lump,nipple discharge, nipple retraction, fixation to the skin or the underlying tissues, and skin ulceration. There are many different factors that can affect male breast cancer including age, ethnicity, geography, socioeconomic status, heredity, hormones, and treatment.

    Breast cancer is uncommon in men. In 2001, it was estimated that 1,500 men had been diagnosed with breast cancer. This is compared to the 192,200 women diagnosed with breast cancer. It was also estimated that 400 men died from this disease while 40,200 women died from this disease.
    Most of the risk factors for breast cancer in men are the same for women. The same tumors are seen in women and men and the signs and symptoms are the same. What's different is that the age of diagnosis in men is about 10 years later than that in women. Also, men have a lower survival rate than women and that may be because men have shorter lives than women and many have other health problems. A study reported that one third of the men with breast cancer died of other diseases.
    There is also evidence that the rates for breast cancer are higher in African American me than white men.

    Breast cancer in men is rare but it is possible. IT is probably rare in men because of their small amount of breast tissue and men produce smaller amounts of hormones like estrogen that are known to affect breast cancer in women. The chances of a man getting breast cancer is 1 in 100 so it would only be 10 men with breast cancer out of 10 million. it has been thought that breast cancer in men is more serious than in omen but it has been discovered that the outcomes are the same as well as the chances of survival.

    Breast cancer in men is far less common than in women, and it is similar to female breast cancer in its etiology, family history, prognosis, and treatment. In approximately 30% of cases of breast cancer in men, the family history is positive for the disease. The American Cancer Society estimates that about 2,000 new cases of breast cancer are diagnosed in men each year and approximately 450-500 men die from breast cancer annually. Male breast cancers account for approximately 1% of all breast cancer cases. It is about 100 times less common among men than among women. The highest rayes of breast cancer are in western Europe and the lowest are in Africa. The rates are specifically high in the UK where 277 men were diagnosed in 2007 and about 70 died of this cancer in 2008.

    Breast cancer can occur in both males and females. It is more common in females; although in males it is more easily spread to other parts of the body. Breast cancer in men is about 100 times less common then in females (the lifetime risk of being diagnosed with breast cancer is 1 in 1,000). Breast cancer affects 1 in 8 women in their lives. There is a similar survival rate of breast cancer in men and women though. In both women and men, one of the ways to get breast cancer is because of obesity.

    The rate of Breast Cancer in men is 1 in 1,000 men or 1% of all breast cancers will be a male breast cancer.In 2001 it said that 1,500 men will get breast cancer compared to the 192,200 women that will be diagnosed. Also it says that 400 males will die from breast cancer than the 40,200 women that will die from breast cancer. The latest news on breast cancer in men is that men can get breast cancer also. Because they have like unproductive ducts that can get cancer.

    Breast cancer in men is 100 times less common than beast cancer in women. Men have a 1 in 1000 chance of getting breast cancer, about 1%. The risk for breast cancer for women depends on your age, for a woman that is 20 years you have a 1 in 1,760 chance of getting breast cancer. The number jumps drastically from age 20 to age 30, at age 30 you have a 1 in 299 chance of getting cancer. Awareness is slowly getting out that men can get breast cancer too, and information on how men can check themselves is also coming into awareness.

  11. The is less tham half percent of 1% of deaths in breast cancer in men.It's about 100 time less common in men than women.The lifetime risk of getting cancer is 1/10th of 1%,about 1 in 1,000.The survival of men and women is comparable by the stage of disease at the time of diagnosis but, men are often diagnosed at a later stage, after the cancer has spread, because they are less likely to report any symptoms than women.
    In the lastes news report that the risk of breast cancer amongs men with a faulty BRCA2 gene was 7.1%.By the age of 70 and 8.4% by the age of 80. These risks are more than enough to increase breast cancer among men in BRCA2 families and to stress the importance of early symptoms with breast cancer.

    Although it is far less common, men can get breast cancer, just as women can. Men have a one-in-1000, or one tenth of a percent risk of becoming diagnosed with this disease. The variety of causes are similar to the ones in women, and include contact with isotope radiation, unusually high levels of estrogen, Klinefelter's Syndrome, and inherited mutations in the BRCA-2 gene. Treatment of the disease in men is similar to the treatment in women, and involves surgery and chemotherapy.

    The overall ratio of female to male breast cancer in the U.S. is 100 to 1. So for every 100 females with breast cancer, there is 1 male with breast cancer. Despite the difference in frequency of breast cancer in females to males, about 1,970 males will be diagnosed this year with breast cancer, and 390 males will die from the disease.

    In recent news, new factors have been discovered that are known to contribute to breast cancer in men. They include: Klinefelter's Syndrome and hyperestrogenism (involved with high estrogen levels), radiation exposure, heredity, liver disorders, alcoholism, obesity, and aging.

    Breast cancer in men is 100 times less likely to develop than breast cancer in women. 1 percent of all breast cancer cases in the US are actually Male breast cancer cases.

    Estimated new cases of male breast cancer in the U.S. are 1970 cases with 390 deaths. Most diagnosis are made at 60-70 years old, though men of any age can be affected. The survival rates of males diagnosed with the disease are much the same to the survival rates of women with the disease. Contrary to popular belief breast cancer in men is not more dangerous than it's female counterpart. This notion probably derives from the fact that most male breast cancer cases are diagnosed at a later stage.

    Both men and women can develop breast cancer, however this is much more common in women, as male breast cancer makes up only 1% of the breast cancers. Both men and women have a small amount of breast tissue within them. Women most likely develop breast cancer more that men because during puberty, hormones produced by females cause the breasts to grow while male hormones prevent breast development. In recent news however, it has been shown that the amount of men developing breast cancer is increasing. The rate seems to be about 2000 men diagnosed annually.

    Breast cancer, though prominent in females, is a rare condition in males. Breast cancer is 100x more possible to occur in women than in men leading The American Cancer Society to estimate that by 2008, breast cancer will take 480 male lives compared to the over 40,000 women who die of breast cancer each year. The rare condition mentioned earlier is called Male Breast Cancer and accounts for only 1% of breast cancers in the world. Male Breast Cancer occurs in most males between the ages of 60 and 70, even though it can develop in men at any age.

    Breast cancer in men is a rare disease for which treatment and management guidelines are scarce.
    This year in the US, more than 1600 men will be diagnosed with breast cancer compared to over 200,000 women who will receive the same diagnosis. An estimated 500 men will die from breast cancer compared with over 40,000 women.
    One difference is that men are diagnosed with breast cancer at a later age than women(68yrs compared to 23yrs).
    Another difference is the frequency of the histological types, and the frequency of expression of steroid hormone receptor and molecular markers. Oestrogen, androgen, and progesterone steroid receptor expression is also higher in men with breast cancer.
    Clinical outcomes for breast cancer in men are similar to those for women when they are matched for age, treatment, and stage of cancer.

    Breast cancer occurs mostly in women, but men can get it, too. However, breast cancer is not very common in men because their breast duct cells are less developed than the cells of women and because their breast cells are not constantly exposed to the growth-promoting effects of female hormones. Male breast cancer is rare. It happens most often to men between the ages of 60 and 70.

    Men on the contrary of many misconceptions can too as women get breast cancer. Breast cancer for both sexes is the uncontrolled growth of the cells of the breast tissue. Although breast cancer in male is only one percent it is just as dangerous if not more because of men's reluctance to rewport symptoms. All types of brest cancers that occur in females can also occur in male although some are rare. The survival rate for women is far more then that of men as a matter of fact.
    Even celebrities such as Peter Criss the drummer of the band KISS had breast cancer and says to men how getting medical treatment early at the first sign of trouble saved his life.

  21. Although breast cancer is more common in women than in men, one in every one hundred breast cancer cases is a man. It is usually unnoticed, unusual and ignored. Men who are most at risk are those over the age of 65, African Americans, those exposed to radiation therapy and those with family history of breast cancer. It is 100 times more common in women than it is in men. In 2003 1600 men were diagnosed compared to the 200,000 women. Breast cancer in men and women contrast in the age of diagnosis the frequency of the histological types, and the frequency of expression of steroid hormone receptor and molecular markers. Less than a year after losing his wife, a man was diagnosed with stage four breast cancer that spread to his bones. He came out of the shower one day and noticed a lump on his chest on only one side.

    For every 100 women affected by breast cancer, 1 man is affected. It represents less than 1% of cancers that affect men. It is believed that breast cancer is affected by the BRCA2 gene, which increases the risk of cancer, and a mans risk of getting breast cancer peaks at age 71. 15-20% of men have a family history of breast cancer as opposed to 7% in the general population, making heredity a very important risk factor. Also, the mortality rate is higher for black men than white men who have the disease. It is treated the same way as female breast cancer is treated, with chemo, radiation, and surgery.

    Breast cancer is cancer originating from breast tissue, most commonly from
    the inner lining of milk ducts or the lobules that supply the ducts with milk.
    American Cancer Society estimates that in 2008 about 1,990 new cases of
    invasive breast cancer will be diagnosed among men and about 450 men will
    die from breast cancer in the United States. Breast cancer is about 100 times less
    common among men than among women and accounts for less than half of
    1% of cancer deaths among men. For men, the lifetime risk of getting breast
    cancer is about every 1 in 1,000. Breast Cancer is therefore more common in Woman
    than in Men.
