Can men enlarge breast without surgery?

What cream are you referring to?  You need to specify which cream you are referring to.  There are many products climbing to help enlarge breasts but as far as I know, there in no good scientific evidence to support these claims.

I usually recommend my patients take about 5-7 days off of work. Do not lift anything heavy until about 6 weeks after surgery. Please ask your surgeon for their advice as they may have different guidelines.

Sickness before surgery can increase the risk of complications, which is why it is typically safer to reschedule your surgery rather than going ahead with it. Please let your surgeon know if you develop any cough or cold so they can decide whether it would be safe to proceed or not.

You need to have a thorough examination and bloodworm to ensure that you are ok for surgery.  It is up to your PS and anesthesiologist to clear you for surgery.  

While every surgeon is different, our recommendations are to stay out of the gym for 3-4 weeks after breast augmentation, and to minimize pec work-outs for 6 months post-op.You can continue with biceps, triceps, lats, deltoid, etc after the initial period of healing - as long as you are careful...

In no way would I suggest you fill your breasts with anything besides FDA approved implants and potentially some fat. Its just not safe. A small implant under the gland in a body builder is a great and reliable operation
