They have the shape and size of an almond, and produce both eggs and female hormones (estrogen and progesterone) that are responsible for shaping and feminine traits to the body and regulate menstruation and pregnancy among other things. Ovarian cancer accounts for 4% of tumors that affect women.

The ovarian cysts are benign tumors that usually disappear spontaneously. If they persist or grow, the doctor can remove them. There are three basic types of malignant tumors, which are formed on the surface of epithelial ovarian carcinoma are known and are the most common.

Also, but much less common, there might be cases of cancer in cells that produce eggs and tissue surrounding the ovary.

The most common metastatic ovarian cancer occur in the peritoneum, which is the sac lining the intestines.

In these cases there is ascites (accumulation of fluid in the abdomen), while if they reach the blood or lymphatic system, cancer cells can travel throughout the body, which increase the likelihood of metastases in other parts of the body.

The neck of the uterus, also called cervix connects the vagina with the uterine cavity that is lined by the endometrium. Cervical cancer is also known as squamous cell carcinoma because the cells lining their surfaces are flat and thin, as if they were scales.

Through the lymph system can extend to any body part, but this happens rarely. It is a tumor with a tendency to grow and be on the same site, once removed. But it tends to spread.

skin cancerWhat is it?

Skin cancer is a disease caused by the development of cancerous cells in any of the layers of the skin.

There are two types: non-melanoma and melanoma.

The non-melanoma cancer is the most common and is called nonmelanoma because they formed from other skin cells are not accumulating pigment (melanocytes). Within this type are all skin cancers less malignant melanoma is less common and more malignant and explained below.

Skin cancer is most prevalent among white skinned people who have spent much time exposed to sunlight, especially when sun exposure occurred in childhood and there were numerous sunburn. Although it may appear anywhere on the skin, is more common than is presented on the face, neck, hands and arms.

This cancer is one of the most common of all cancers, and diagnosed an estimated two million new cases per year worldwide.

In recent years, the incidence of malignant melanoma has increased dramatically, has multiplied by 3.3 in males and 2.5 in women over the last twenty years in Spain. Despite this, less than 3% of all tumors and early detection campaigns have allowed the mortality is reduced by 30% since the seventies.

You can recognize a change in the appearance of the skin, like a wound that does not heal or a small bump. You may also see a red, rough or scaly skin with a tendency to grow.

Any changes or abnormality of the skin, one must see the doctor. It can extract and analyze a sample (biopsy) to check whether a tumor is malignant or not.
