What causes classical seminoma?

What causes classical seminoma?

Causes. A seminoma arises from germ cells that grow uncontrollably. Germ cells are the cells that form an embryo in a mother’s womb. Later on in development, germ cells are supposed to mature into sperm-producing cells within the male testicles.

Is seminoma a cancer?

A type of cancer that begins in germ cells in males. Germ cells are cells that form sperm in males or eggs in females. Seminomas occur most often in the testicle, but they may also occur in other areas of the body, such as the brain, chest, or abdomen.

What percentage of testicular cancer is seminoma?

Within germ cell tumors are three types of testicular cancers: Seminomas may be slightly more common, accounting for about 55 percent of all testicular germ cell tumors in the United States, according to a 2014 study in Andrology.

Is seminoma cancer curable?

Testicular cancer is a disease that occurs when cancerous (malignant) cells develop in the tissues of a testicle. The development of cancerous cells in both testicles can occur, but is very rare. Testicular cancer is the most common cancer in men aged 20 to 35. The disease usually is curable.

Which is worse seminoma or nonseminoma?

The cancer is in the testes, but it can spread to the lymph nodes. Lymph node involvement is either treated with radiotherapy or chemotherapy. Seminomas are very sensitive to radiation therapy. Nonseminoma: This more common type of testicular cancer tends to grow more quickly than seminomas.

What does a seminoma feel like?

The most common symptom is a lump or a swelling in your testicle. Lumps can be as small as a pea. Swelling can feel like an irregular thickening on your testicle. These things are often painless, but you might feel some discomfort.

Is seminoma worse than Nonseminoma?

Seminomas are very sensitive to radiation therapy. Nonseminoma: This more common type of testicular cancer tends to grow more quickly than seminomas.

Can you live a long life after testicular cancer?

The general 5-year survival rate for men with testicular cancer is 95%. This means that 95 men out of every 100 men diagnosed with testicular cancer will live at least 5 years after diagnosis. The survival rate is higher for people diagnosed with early-stage cancer and lower for those with later-stage cancer.

Can you live a full life after testicular cancer?

How does seminoma spread?

Most seminoma tumors grow more slowly than non-seminoma tumors. But they can spread to the lymph nodes or lungs. In some cases, they can reach other parts of the body like your brain or liver. Seminoma tumors do respond better to radiation therapy and chemotherapy than non-seminomas.

Which is the best description of a seminoma?

Seminomas, which are germ-cell tumors (GCTs), are divided into two pathological categories: classical and spermatocytic [1]. OCT-4 (cat.

Can a seminoma be a form of testicular cancer?

About 30% of patients with testicular seminoma have mild increases of hCG. 6  Another tumor marker of testicular cancer is called alpha-fetoprotein (AFP). Pure seminomas do not produce AFP. However, some germ cell tumors are mixed, meaning they have both seminoma and non-seminoma areas.

How old do you have to be to have seminoma cancer?

It is a slow-growing tumor that is generally found in men who are between 30-40 years of age. Generally, the cancer is only in the testicles although it may spread to the lymph nodes. This tumor is also referred to as “Classical Seminoma” or “Pure Seminoma”. The ICD9 Code for this disorder is 186.

What’s the difference between seminoma and mixed germ cell cancer?

Among the different stages of germ cell tumors, pure seminomas tend to be treated one way, and non-seminomas and mixed germ cell tumors are treated another way. In this stage, the cancer has not spread outside the testicle, and tumor marker levels (like HCG and AFP) are not elevated.
