Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include:

• Growth and development
• Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature
• Sexual function
• Reproduction
• Mood

If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels.

In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.

Cancer is a disease in which abnormal cells in the body grow out of control and form a tumor. Ovarian cancer is a cancerous tumor that forms in the tissues of an ovary. The ovaries are a pair of female reproductive glands that make eggs and female hormones.

There are a few different types of ovarian cancer. The most common type is epithelial cancer. It begins in the cells that cover the ovary.

There are also two related types of epithelial cancer that can spread to the ovaries:

• Fallopian tube cancer forms in the tissue lining a fallopian tube. The fallopian tubes are a pair of long, slender tubes on each side of the uterus. The uterus is the female reproductive organ where a baby grows during pregnancy.
• Primary peritoneal cancer forms in the tissue lining the peritoneum. Your peritoneum is a tissue lining that covers the organs in the abdomen (belly).

These two cancers are similar to ovarian cancer, and they have the same treatments. So some medical experts also consider those two types as ovarian cancer.

Some other rarer types of ovarian cancer are malignant germ cell tumors and stromal tumors.

Ovarian cancer happens when there are changes (mutations) in the genetic material (DNA). Often, the exact cause of these genetic changes is unknown.

Most ovarian cancers are caused by genetic changes that happen during your lifetime. But sometimes these genetic changes are inherited, meaning that you are born with them. Ovarian cancer that is caused by inherited genetic changes is called hereditary ovarian cancer.

There are also certain genetic changes that can raise your risk of ovarian cancer, including changes called BRCA1 and BRCA2. These two changes also raise your risk of breast and other cancers.

Besides genetics, your lifestyle and the environment can affect your risk of ovarian cancer.

Certain people are more likely to develop ovarian cancer. They include those who:

• Have a family history of ovarian cancer in a mother, daughter, or sister
• Have inherited changes in the BRCA1 or BRCA2 genes.
• Have certain other genetic conditions, such as Lynch syndrome
• Have endometriosis
• Took hormone replacement therapy
• Are overweight or have obesity
• Are tall
• Are older, especially those who have gone through menopause

Ovarian cancer may not cause early signs or symptoms. By the time you do have signs or symptoms, the cancer is often advanced.

The signs and symptoms may include:

• Pain, swelling, or a feeling of pressure in the abdomen or pelvis
• Sudden or frequent urge to urinate (pee)
• Trouble eating or feeling full
• A lump in the pelvic area
• Gastrointestinal problems, such as gas, bloating, or constipation

To find out if you have ovarian cancer, your health care provider:

• Will ask about your medical history, including your symptoms
• Will ask about your family health history, including relatives who have had ovarian cancer
• Will do a physical exam, including a pelvic exam
• Will likely do imaging tests
• May do blood tests such as a CA-125 blood test

Often the only way to know for sure that you have ovarian cancer is by having a biopsy of the tissue. A biopsy is done during surgery to remove the tumor.

Treatments for ovarian cancer may include:

• Surgery to remove as much of the cancer as possible
• Chemotherapy
• Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells

Your provider may suggest that you have genetic testing to look for the gene changes that raise the risk for ovarian cancer. Knowing whether or not you have the gene change may help your provider decide on your treatment plan.

Testicular cancer is a cancer that develops in the tissues of one or both testicles. The testicles, or testes, are part of the male reproductive system. They make male hormones and sperm. They are two egg-shaped glands inside the scrotum, a sac of loose skin that lies below the penis. You can get cancer in one or both testicles.

Testicular cancer is very rare. You can get it at any age, but it is most common in men between the ages of 20 and 39. It is also more common in those who:

• Have had abnormal testicle development
• Have had an undescended testicle, a condition in which one or both testicles fail to move into the scrotum before birth
• Have had testicle cancer before
• Have a family history of the cancer
• Are White

The symptoms of testicular cancer may include:

• A painless lump or swelling in either testicle
• A change in how the testicle feels
• A dull ache in the lower abdomen (belly) or the groin (the area where the thigh meets the abdomen)
• A sudden build-up of fluid in the scrotum
• Pain or discomfort in a testicle or in the scrotum

To find out if you have testicular cancer, your health care provider may use:

• A physical exam.
• Blood tests.
• An ultrasound of the testicles.
• An inguinal orchiectomy, which is a procedure to remove the entire testicle. A tissue sample from the testicle is viewed under a microscope to check for cancer cells.

Testicular cancer can usually be cured.The treatment options include:

• Surgery (if the testicle has not already been removed during diagnosis).
• Radiation therapy.
• Chemotherapy.
• High-dose chemotherapy with stem cell transplant.
• Surveillance, which might be done after surgery. It means that your provider will closely follow your condition with regular exams and tests. You won't get any further treatment unless there are changes in your test results.

Some of the treatments may also cause infertility. If you may want to have children later on, you should consider sperm banking before treatment.

After you have finished your treatment, you will need regular follow-up testing to make sure that the cancer has not come back. If you have had cancer in one testicle, you have a higher risk of getting cancer in the other testicle. So it's important to check the other testicle regularly and let your provider know if you notice any changes or unusual symptoms.
