WEDNESDAY, July 16 (HealthDay News) -- Anti-rejection drugs given after organ transplants may be the reason why 15 percent to 20 percent of individuals who receive such transplants have a higher risk of developing cancer within the next decade.

The good news is that targeted therapies could diminish the risk, said Harvard researchers reporting in the July 15 issue of Cancer Research.

THURSDAY, May 15 (HealthDay News) -- Researchers say they may be able to prevent the tissue damage that lung diseases, such as emphysema, cause by treating the patient with doxycycline, an antibiotic commonly used to treat acne.

In experiments on mice, doxycycline -- which is also used to treat common ailments such as sinusitis and urinary tract infections -- appears to counter low levels of VEGF, a protein that helps to maintain healthy lung tissue but is in unusually low levels in people with emphysema.
