This is described as a medical mystery: why there is a decrease in the number of tumors in general when it is increasing thyroid cancer?
The diagnosis for this type of cancer that affects the gland in the neck is in fact estimated to steadily increase at a rate of increase of around 6% per year according to an analysis provided by the U.S. National Cancer Institute.
Researchers now know to give an account that is linked to increased technological capabilities of medicine, and in particular to the fact that today we do many more scans to inspect neck pain and conditions of arterial plaque and that this contributes to the discovery even tiny tumors in the thyroid, which once would have remained unnoticed and that in most cases did not express any malign evolution and dangerous to health.

It ‘very rare for a man aged under 35 to get breast cancer, but the probability of developing the disease increases with age, with most being detected between 60 to 70 years. Family history of breast cancer in a close female relation and a history of exposure to radiation of the chest may also increase the risk.
The most obvious risk for developing breast cancer seems to be in men who have had an abnormal enlargement of their breasts (called gynecomastia) in response to drugs or hormone treatments, or even some infections and poisons. Individuals with a rare genetic disorder called Klinefelter’s syndrome, which often have gynecomastia, as part of the syndrome, are particularly prone to develop breast cancer. Men with severe liver disease tend to have lower levels of male hormones (androgens) and higher levels of female hormones (estrogen) by making an increased risk of developing gynecomastia and breast cancer. Furthermore, diseases of the testes, such as mumps orchites, an injury to the testicles, or an undescended testicle increase the risk of breast cancer in men.

Even if people do not have breasts like women, who have a small amount of breast tissue. Actually my breasts “of an adult man are similar to the breasts of a girl before puberty, and consist of a few ducts surrounded by breast and other tissues. In girls, this tissue grows and develops in response to female hormones, but in men – who do not secrete the same amounts of these hormones – this tissue does not develop.
However, because it is still the breast tissue, men can develop breast cancer. In fact, men get the same types of breast cancers that women do, but tumors that involve the production of milk and the conservation of regions of the breast are very rare. According to the American Cancer Society, about 2,300 cases of breast cancer will be diagnosed in men in 2009.

Digital rectal finger is inset into the rectum and from there you can highlight an area hardest or irregular, which could be an indication of both a benign and malignant pathology in both the colon, or prostate, remember that the prostate is located in front of the colon. This exploration is part of the clinical examination of the patient.
PSA test: PSA stands for prostate specific antigen English, this test proved very useful because the PSA is increased in prostate cancers but may also increase other pathologies. It seeks its presence in the blood, so for study should be performed the extraction of venous blood from the patient.
Urine test: This test is less specific, but it serves to confirm the presence of blood in the urine or other abnormality. It’s a little specific examination.

It is a cancer whose treatment as with other cancers should be individualized, especially taking into account the disease and how advanced it, the biological status of the patient, his age and life expectancy of the patient.
Surgery.Primary surgical options for prostate cancer can be variable, only the affected part of the prostate in its entirety, and also may be required removal of lymph nodes, or segments of neighboring organs.
The removal of the entire prostate with surrounding tissue is called radical prostatectomy. This can be done via perineal or retropubic.
In some cases also may be indicated to remove the organ that produces the hormone that stimulates the prostate to creezca. In that case the hormone is testosterone and its main producer is the testicles can get to make the extirpation of them performing a bilateral orchiectomy.

* Colposcopy. It uses a colposcope, a device with lenses that increase the visibility of the doctor and to assess the cervix and vagina
* Biopsy. A method for sampling the cervix and evaluated under a microscope.
To assess the extent of the disease and suggest the type of cancer treatment to follow can also be taken:
* X-rays To check whether the cancer has not spread to the lungs.
* CT. It is an X-ray machine with a computer to make pictures of organs.
* MRI. To evaluate images of the pelvis and abdomen.

Radiation therapy uses particles similar to those of X-rays, but of higher energy capable of penetrating into the body.
This technique for cancer treatment acts on the tumor, destroying the malignant cells and preventing them from growing and reproducing, but also destroys normal tissues temporarily, so that radiotherapy has side effects. The advantage is that healthy cells have greater capacity for regeneration than cancer, so the body recovers from the damage once it has managed to remove the tumor and treatment is completed.
Radiation therapy can be administered either as monotherapy or as adjunct to surgery or chemotherapy. When the previously radiated area affected by the tumor, its size is reduced further by facilitating the surgeon’s intervention. In the event that received radiation after undergoing surgery, the goal is to destroy cells that have been left after excision.
