It used to be that smoking and drinking alcohol were the biggest risk factors for cancers that develop in the mouth and throat. Those trends may be changing, according to a new study.

Many assume that once patients are diagnosed with a disease, they automatically begin receiving treatment for that condition — but researchers behind a new study warning that this may not be the case for many patients with hepatitis C.

Some people with hepatitis C experience serious side effects from or do not respond to interferons, the typical treatment for the disease. Fortunately, new research has shown promising results for a different type of treatment.

HIV/AIDS treatment has helped lengthen patients' lives. But as they live longer, people with HIV may have to be especially watchful for health problems related to age, including the possibility of weaker bones.

Most, if not all, cervical cancers are caused by the human papillomavirus (HPV). There are 40 different types of this virus. HPV types linked to cervical cancer may be different in women of different races.

There are vaccines that protect against the human papillomavirus (HPV). These vaccines are often recommended for people with autoimmune diseases who are prone to infection. But it seems that many of these folks may not be getting the HPV vaccine.

People at risk for certain infectious diseases are usually disqualified from being blood donors. However, new research suggests that they may still be safe organ donors.

Reliable and consistent care for HIV-infected people is a necessity. Using multiple care centers for treatment may not allow patients to get the right amount or kind of care.

Hepatitis, or inflammation of the liver, is often caused by infection with one of the hepatitis viruses. But reports are surfacing of a non-viral form of the disease with connections to a dietary supplement.

One of the only vaccines that is known to prevent some forms of cancer is the HPV vaccine. Those who might worry about its safety have no reason to fear.
