When we think of breast cancer, we automatically produce a pink ribbon, an extensive awareness campaign and efforts through various channels, a fund-raising walk-thons, which remind us that breast cancer is a malignant disease that affects thousands of women each year.
Because of its high incidence among the female population, breast cancer is usually thought that women health skrbi.Koncept that breast cancer may actually be diagnosed in men is puzzling to some. Breast cancer in men accounts for less than 1% of all cases of breast cancer, but it can be fatal if left untreated and undetected. In 2009 it was estimated that 1910 people are diagnosed with breast cancer and 440 lost the battle in that same year.
How is it possible for people to develop breast cancer is a legitimate question considering that the term is associated with a frontal area of the upper torso of a woman. In women, this body part is called the breast, while for men it is called prsa.Odgovor to the previous question is in the anatomical structure dojke.Dojke consists of three distinct parts: the lobules - the milk producing glands (in women), ducts - tiny tubes that carry milk lobules to the nipple, and the stroma - fatty and connective tissue around the tubes and lobules, and blood and lymph vessels. Before puberty, both males and females have a small amount of breast tissue and some failures. Once puberty is reached, the differences in the anatomy of the breast become evident in both sexes. In women, increased production of female hormones (estrogen and progesterone) cause the channels to grow in the lobules form, and the amount of stroma to increase. In men, the breast tissue is prevented from increasing male hormone, but the initial tubes and lobules of birth are still present.
Breast cancer develops in the inner tissue lining the milk ducts and the lobules. Given the fact that men also have a pipe and several lobules, it is possible to develop cancer in the tkivima.Niska incidence of breast cancer in men is attributed to the reduced amount of male breast tissue compared with that of dojke.Prednost have reduced the amount of breast tissue is that any abnormal growths or bumps can be easily noticed. Unfortunately, because breast cancer is so rare in men, a majority believes that the disease affected only women, men will often ignore early signs or attribute them to the wrong cause (such as infection or injury ).
cancer, in general, the results when the normal growth and physical process of dying cells is oslabljen.Posljedica this dysfunction is that old cells do not die when they should, but the new cells to keep growing when the body does not need. When this disorder occurs, new cells form a mass of tissue that eventually becomes tumora.Nenormalan new cell growth is attributed to genetic mutations. What causes these mutations is still a mystery to the medical field, but several links between diseases and internal (genetic) and external (environmental) factors are established. Some of the risk factors associated with breast cancer in men are: radiation exposure, hyperestrogenism, Klinefelter's syndrome, liver cirrhosis, family predisposition, and age (men with age between 60 and 70 years are at increased risk of developing breast cancer ).
When considering the radiation risk is higher in men who were treated with ionizing radiation for various forms of cancer in the breast. Hyperestrogenism refers to increasing the production of estrogen in men causes breast tissue to grow - a condition known as gynecomastia.Slična situation is present in men diagnosed with Klinefelter syndrome. This syndrome is a rare hereditary condition in which the chromosomal make-up man consists of XXY instead of the normal XY (X chromosome is inherited from the mother and the Y chromosome is inherited from the father). Extra X chromosome determines the increased production of estrogen that causes men to develop breasts to have less body and facial hair, small testes, and inability to produce and spermu.Rizik of developing breast cancer in men affected by this syndrome is 50 percent higher than the normal male population.
The link between breast cancer and cirrhosis of the liver may sound confusing at first. Cirrhosis is caused by genetic disorders, but most often results from chronic alcoholism or chronic viral hepatitis. The role of the liver to produce binding proteins that regulate the release and transport of male and female hormones through the blood. When functioning normally affects the liver cirrhosis, toxic substances tend to accumulate in the liver, resulting in its natural function. Cirrhotic men have higher levels of estrogen in the bloodstream, which increases their risk of developing breast cancer.
family history relating to the history of breast cancer in female relatives of affected people. Men can also inherit genetic mutations (especially BRCA-2 gene) is responsible to develop breast cancer in women. This gene is associated with ovarian cancer in women and prostate cancer in men.
While all of these facts may seem frightening and feel out of our power to control (particularly genetic factors), it is important for people to become familiar with early signs of breast cancer. One sign that the tumor may be developing a presence of non-painful mass (typically 2.5 inches in diameter, on average) below bradavice.Koža around the nipple may undergo noticeable changes, such as ulceration, dimpling / puckering, redness of the nipple and even the nipple retracts. In some instances, opaque or bloody discharge from the nipple may be noticed.
Breast cancer in men can be effectively treated if detected at an early stage of development before it spreads to other parts tijela.Mogućnosti treatment varies from surgery to chemotherapy, radiation and hormonal terapija.Metode treatment depends on the stage cancer at the age of the patient and his general health and the extent of the cancer (whether present in both breasts or just one, or if it spread to adjacent areas), which can only be decided by a medical team in collaboration with the patient.
