Testicular Disorders

Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.

Thyroid Cancer

What is thyroid cancer?

Thyroid cancer is a cancer that starts in the tissues of the thyroid. Your thyroid is a small, butterfly-shaped gland in the front of your neck. It makes hormones that control the way the body uses energy. These hormones affect nearly every organ in your body and control many of your body's most important functions. For example, they affect your breathing, heart rate, weight, digestion, and moods.

What are the different types of thyroid cancer?

There are different types of thyroid cancer; the main ones include:

• Differentiated thyroid cancer, which includes papillary cancer and follicular cancer
• Medullary thyroid cancer
• Anaplastic thyroid cancer

Who is more likely to develop thyroid cancer?

Certain people are more likely to develop thyroid cancer. Your risk is higher if you:

• Are between ages 25 and 65
• Are a woman
• Are Asian
• Were exposed to certain types of radiation, including from radiation treatments to your head or neck as a child or from a radiation emergency
• Have had a goiter (enlarged thyroid)
• Having certain genetic conditions, including certain types of multiple endocrine neoplasia
• Have a family history of thyroid cancer or thyroid disease

What are the symptoms of thyroid cancer?

Thyroid cancer may not cause symptoms at first. It is sometimes found during a routine physical exam. You may get signs or symptoms as the cancer gets bigger. The symptoms may include:

• A lump (nodule) in the neck
• Trouble breathing
• Trouble swallowing
• Pain when swallowing
• Hoarseness or other changes to your voice that do not get better

How is thyroid cancer diagnosed?

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

• A physical exam, including checking your neck for swelling, lumps, or anything that seems unusual
• A medical history
• Thyroid tests
• Other blood or imaging tests
• A biopsy

What are the treatments for thyroid cancer?

Treatment for thyroid cancer depends on the type of cancer you have and whether the cancer has spread. Often, more than one type of treatment may be needed. The treatment options include:

• Surgery.
• Radiation therapy, including radioactive iodine therapy.
• Chemotherapy.
• Thyroid hormone therapy.
• Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells.
• Watchful waiting, which means that you don't get treatment right away. Your regularly checks to see if your signs or symptoms appear or change.

Uncommon Infant and Newborn Problems

It can be scary when your baby is sick, especially when it is not an everyday problem like a cold or a fever. You may not know whether the problem is serious or how to treat it. If you have concerns about your baby's health, call your health care provider right away.

Learning information about your baby's condition can help ease your worry. Do not be afraid to ask questions about your baby's care. By working together with your health care provider, you make sure that your baby gets the best care possible.

X-Rays

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less and look gray. Air absorbs the least, so lungs look black.

The most familiar use of x-rays is checking for fractures (broken bones), but x-rays are also used in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer.

When you have an x-ray, you may wear a lead apron to protect certain parts of your body. The amount of radiation you get from an x-ray is small. For example, a chest x-ray gives out a radiation dose similar to the amount of radiation you're naturally exposed to from the environment over 10 days.
