What is prostate cancer?
Cancer is a disease in which cells in the body grow out of control. Prostate cancer begins in the cells of the prostate. The prostate is a gland in the male reproductive system. It lies just below the bladder. It makes fluid that is part of semen.
Prostate cancer is one of the most common types of cancer. It often grows very slowly. If it does not spread to other parts of the body, it may not cause serious problems. But sometimes prostate cancer can grow quickly and spread to other parts of the body. This kind of prostate cancer is serious.
What causes prostate cancer?
Researchers don't know for sure what causes prostate cancer. They do know that it happens when there are changes in the genetic material (DNA).
Sometimes these genetic changes are inherited, meaning that you are born with them. There are also certain genetic changes that happen during your lifetime that can raise your risk of prostate cancer. But often the exact cause of these genetic changes is unknown.
Who is more likely to develop prostate cancer?
Anyone who has a prostate can develop prostate cancer. But certain factors can make you more likely to develop it:
- Age. Your chance of developing prostate cancer increases as you get older. Prostate cancer is rare in people under age 50.
- Family health history. Your risk of prostate cancer is higher if you have a parent, sibling, or child who has or has had prostate cancer.
- Race. African Americans are more likely to get prostate cancer. They're also more likely to:
- Get prostate cancer at a younger age.
- Have more serious prostate cancer.
- Die from prostate cancer.
What are the symptoms of prostate cancer?
Prostate cancer doesn't always cause symptoms, especially at first. If it does cause symptoms, they may include:
- Problems urinating (peeing), such as:
- A urine stream that's weak, hard to start, or starts and stops
- Suddenly needing to urinate right away
- Urinating often, especially at night
- Pain or burning when urinating
- Blood in your urine or semen
- Pain in your lower back, hips, or pelvis that does not go away
- Painful ejaculation (the release of semen through the penis during orgasm)
But many of these symptoms may be from other common prostate problems that aren't cancer, such as an enlarged prostate.
You should discuss your prostate health with your health care provider if you:
- Have symptoms that could be prostate cancer
- Have a high risk for developing prostate cancer
- Had a screening test that suggests you could have prostate cancer
What are prostate tests and how is prostate cancer diagnosed?
Tests which check for prostate cancer include:
- A digital rectal exam (DRE). In this exam, your provider feels your prostate for lumps or anything unusual by inserting a lubricated, gloved finger into your rectum.
- A prostate-specific antigen (PSA) blood test. A high PSA blood level may be a sign of prostate cancer. But many other things can cause high PSA levels, too.
- Imaging tests. These tests may use ultrasound or MRI to make pictures of your prostate.
If these tests show that you might have prostate cancer, the next step is usually a prostate biopsy. A biopsy is the only way to diagnose prostate cancer.
During a biopsy, a doctor uses a hollow needle to remove some prostate tissue. The tissue is studied under a microscope to look for cancer cells.
What are the treatments for prostate cancer?
Your treatment options usually depend on your age, your general health, and how serious the cancer is. Your treatment may include one or more of options:
- Observation,which is mostly used if you are older, your prostate cancer isn't likely to grow quickly, and you don't have symptoms or you have other medical conditions. Your doctor will keep checking on your cancer over time so to see whether you will need to start treatment for the cancer. There are two types of observation:
- Watchful waiting means having little or no testing. If symptoms begin or change, you will get treatment to relieve them, but not to treat the cancer.
- Active surveillance means having regular tests to see if your prostate cancer has changed. If the tests show the cancer is starting to grow or if you develop symptoms, then you will have treatment to try to cure the cancer.
- Surgery to remove your prostate gland may be an option if your cancer hasn't spread outside of your prostate.
- Radiation therapy uses high energy to kill cancer cells or prevent them from growing.
- Hormone therapy blocks cancer cells from getting the hormones they need to grow. It may include taking medicines or having surgery to remove the testicles.
- Chemotherapy uses medicines to kill cancer cells, slow their growth, or stop them from spreading. You might take the drugs by mouth, as an injection (shot), as a cream, or intravenously (by IV).
- Targeted therapy uses drugs or other substances that attack specific cancer cells. This treatment causes less harm to healthy cells than radiation therapy or chemotherapy.
- Immunotherapy helps your own immune system to fight cancer.
Can prostate cancer be prevented?
Making healthy lifestyle changes may help to prevent some prostate cancers. These changes include:
- Being at a healthy weight
- Quitting smoking
- Getting enough exercise
- Eating healthy foods

What does your skin do?
Your skin is your body's largest organ. It covers the entire outside of your body. There are many ways that your skin protects your body and helps keep you healthy. For example, it:
- Holds body fluids in, which helps prevent you from getting dehydrated
- Keeps out harmful germs, which helps prevent infections
- Helps you feel things like heat, cold, and pain
- Helps control your body temperature
- Makes vitamin D when the sun shines on it
- Shields your body against heat and light
What problems and conditions can affect your skin?
There are many different problems and conditions which can affect your skin. Some of them can cause uncomfortable symptoms, such as itching, burning, redness, and rashes. They might also affect your appearance. Some of the more common skin conditions include:
- Acne, which causes pimples when hair follicles under your skin get clogged up
- Burns
- Cuts and scrapes
- Dandruff, flaking of the skin on your scalp (the top of your head)
- Eczema (atopic dermatitis), which causes inflammation, redness, and irritation of the skin
- Hives, which are red and sometimes itchy bumps on your skin
- Insect bites
- Psoriasis, which causes itchy, scaly red patches
- Skin cancer
- Skin infections
How can I keep my skin healthy?
Since your skin protects your body in many ways, it's important to try to keep your skin healthy. For example, you can:
- Wear the right protective equipment, like gloves, long sleeves, knee and elbow pads, or helmets to protect against cuts, bumps and scrapes.
- If you do get a cut or scrape, clean it right away with soap and warm water. Put on a bandage to protect it while it heals.
- When you are spending time outdoors, wear long sleeves and pants and use insect repellant to prevent insect bites.
- Prevent sunburn by covering up and using sunscreen when outdoors.
- Wash your hands often with soap and water.
- When you take a shower or bath, use warm (not hot) water. Use mild cleansers and wash gently (don't scrub).
- Use moisturizers, like lotions, creams, or ointments, to prevent dry skin.

Warts are growths on your skin caused by an infection with humanpapilloma virus, or HPV. Types of warts include :
- Common warts, which often appear on your fingers
- Plantar warts, which show up on the soles of your feet
- Genital warts, which are a sexually transmitted infection (STI)
- Flat warts, which appear in places you shave frequently
In children, warts often go away on their own. In adults, they tend to stay. If they hurt or bother you, or if they multiply, you can remove them. Chemical skin treatments usually work. If not, various freezing, surgical and laser treatments can remove warts.
