Letrozole has been used for ovarian stimulation by fertility doctors since 2001 because it has fewer side-effects than clomiphene ( Clomid ) and less chance of multiple gestation. A study of 150 babies following treatment with letrozole or letrozole and gonadotropins presented at the American Society of Reproductive Medicine 2005 Conference found no difference in overall abnormalities but did find a significantly higher rate of locomotor and cardiac abnormalities among the group having taken letrozole compared to natural conception.  A larger, follow-up study with 911 babies compared those born following treatment with letrozole to those born following treatment with clomiphene.  That study also found no significant difference in the rate of overall abnormalities, but found that congenital cardiac anomalies was significantly higher in the clomiphene group compared to the letrozole group. Despite this, India banned the usage of letrozole in 2011, citing potential risks to infants.  In 2012, an Indian parliamentary committee said that the drug controller office colluded with letrozole's makers to approve the drug for infertility in India and also stated that letrozole's use for infertility was illegal worldwide;  however, such off-label uses are legal in many countries such as the US and UK.  
Hi Karl. I’m really happy for you that you made it through cancer. As you put on weight it’s natural that your fat deposits on your chest became bigger too. Also, the medications probably messed up your hormones. Definitely, a healthy diet and regular exercises would be helpful. I recommend you to consult your condition with a doctor to establish if you have just fat on your chest (pseudo gynecomastia) or some hormonal changes in your breast tissue (gynecomastia). As there are different medicines for both conditions you will be better off knowing what exactly you have.
