Breast Cancer In Men
The age of onset is usually around 60 years.The histologic types (classes of tumor as the aspect of the tissue under a microscope), are generally the same as in women.
What are the risk factors?
They are much less defined than in women.
- Inherited or genetic factors: the most important seem to be hereditary or genetic factors. It seems to be more common in men women whose close family have had breast cancer, ovary or uterus and who is genetically detected some kind of predisposition. If you suspect this type of hereditary cancer, it is desirable to perform a chromosome study of family, to better identify this risk. and even a possible diagnosis of the disease in early stages. However, these genetic characteristics can not be identified in all families of suspected hereditary breast cancer.The tests are performed in special centers, and all patients should be tested.
– It has been found that some men with breast cancer had a greater frequency of cancer in other body locations.
– Endocrinological factors: treatment with hormones (estrogen) cause an increased risk of developing this disease.
– Other diseases: diseases such as Klinefelter syndrome, gynecomastia (enlarged breasts in men), liver disease, or alcoholism , have been linked to an increased risk of developing breast cancer in males.
– Environmental factors: labor history with radiation, blast furnaces, press shops, or electromagnetic fields have been associated with this type of cancer.
Symptoms of breast cancer in men
Most often, the man noticed a lump in the breast, usually hard consistency and very mobile. It can be painful or not.Generally, the male doctor’s visit later in life than women, because few suspect that may be a breast cancer, by the rarity of this disease in males. In addition, when diagnosed, the tumor is usually more advanced than women, because the male has less fat and connective tissue, so that takes less time to tumor spread to lymph nodes and bloodstream.
Other times, the man can see that what exists is a skin change without notice package, becoming withdrawn aspect, aging, or changes in the nipple irritation, also retracted into the breast. You can become red and inflamed skin in some cases, obstruction of small lymphatic vessels which prevents fluid drainage.
Breast Cancer Diagnosis
– Same as in women.
– The first test is usually a mammogram , it may be more difficult to perform than in women, as there is less breast tissue.
– Needle aspiration (FNA), to remove the tumor cell material and examine it under a microscope. You can provide a definitive diagnosis almost.
– Biopsy of the nodule.Provides accurate diagnosis of benign or malignant tumor.Sometimes surgery is done directly and anesthesia generally in the same operation that is therapeutic.
Treatment of breast cancer in men
– Treatment usually does not differ from that applied to women.
– Surgery is usually a modified radical mastectomy: removal of the entire breast, while retaining some muscle structures.Similarly, be surgically removed most axillary nodes that are possible.
– Radiation -applied area mastectomy and axillary in cases in which they are involved nodes.
– Chemotherapy : is administered as an intravenous medication cycles every three weeks.
– Hormone: anti-hormonal drug as breast cancer in men usually respond to stimulation of growth hormones like estrogen exercise.The most commonly used drug is tamoxifen. There are methods for suppressing the input surgical tumor hormone can also be used in specific cases as treatment (removal of testes, pituitary or adrenal glands).
What is the prognosis of breast cancer in men?
In the same phases of the disease, the prognosis is the same as in women.The problem with the man is that his disease is usually diagnosed at an advanced stage phases, with the easiest tumor growth that we have explained, and the time taken to see a doctor and be diagnosed, to imagine that there can be no such cancer in a man.
The factors that influence this outcome are: the involvement of the lymph nodes under the arm, tumor size, delay in diagnosis and histology (microscopic appearance), among others.
