About 50 types of cancer have been added to the list of diseases eligible for coverage in a compensation program for people who became sick after the World Trade Center collapse on September 11, 2001, officials said Monday.

The National Institute for Occupational Safety and Health said it had confirmed a recommendation made in June to include the cancers, which break up into 14 categories.

An outbreak of the Ebola virus has killed 15 people in northeastern Congo and the local communities are quickly learning how frighteningly deadly the disease is, and how to prevent its spread.

"Ebola entered my house and I did not know what it was," said Gabriel Libina Alandato, who survived the hemorrhagic fever. "My three daughters and their mother died in August, but it is only when I was taken to the quarantine center that I learned about the disease."

"Are you falling asleep after dinner?"

"Do you have a decrease in libido?"

Mammograms aimed at finding breast cancer might actually raise the chances of developing it in young women whose genes put them at higher risk for the disease, a study by leading European cancer agencies suggests.

The added radiation from mammograms and other types of tests with chest radiation might be especially harmful to them and an MRI is probably a safer method of screening women under 30 who are at high risk because of gene mutations, the authors conclude.

An AIDS awareness campaigner and his lawyers said Friday they are taking a groundbreaking test case to Zimbabwe's highest court to force police and prison authorities ensure HIV sufferers get their life prolonging medication.

A common dietary supplement could treat a rare form of autism which has been found to be linked to an amino acid deficiency, a study published Thursday in the journal Science has found.

U.S. researchers were able to isolate a genetic mutation in some autism patients which speeds up metabolism of certain amino acids.

Argentina's "miracle baby," born premature and declared dead in April and then found alive 12 hours later at the morgue, has been cleared to go home, the hospital said Thursday.

Singapore registered its worst level of air pollution for the year on Friday as smoke from forest fires in Indonesia blew over the city-state, triggering a health warning.
