(February 9, 2009 - Insidermedicine) From Seattle - According to a study in the journal Cancer, smoking marijuana may increase the risk of testicular cancer. In a study of over 1,300 men, researchers found that, compared to those who had never smoked marijuana, current users had a 70% increased risk of testicular cancer. The risk increased by 40% in men who smoked marijuana less than once a week and doubled in those who smoked it at least once a week
 
From North Carolina - According to research in the Archives of Internal Medicine, corticosteroid use could increase the risk of pneumonia. In a study of 18 randomized trials involving nearly 17,000 people, researchers found that long-term corticosteroid use among those with chronic obstructive pulmonary disease significantly increased the risk of pneumonia. However, long-term use did not lead to a significantly increased risk of death.
 
And finally, from Texas - According to research in the journal Cancer, pregnancy may not affect breast cancer survival. In a study of over 650 women with breast cancer, researchers found that 16% had pregnancy-associated breast cancer. The researchers discovered that, contrary to previous findings, rates of cancer recurrence, spread and survival were the same among women with PABC, compared to other breast cancer patients.
