Hopefully not, but circumcision can have complications.
The risk of serious complications - like severe infections, amputation of the penis, and death - is low, but real. The risk of complications increases if circumcision is done irresponsibly early, e.g. as per Jewish custom.
Edit: and of course, the published complication rates are usually for circumcisions performed by qualified practitioners under typically sterile conditions. They wouldn't include stuff like this:

But who are we to second-guess this time-honoured practice? It would be
cultural imperialism to suggest that mohels shouldn't suck on babies' open wounds, right?
CIRCUMCISION: PROS AND CONS
WHAT ARE THE PROS?
Some of the reasons you may want to circumcise are:
Lowers the risk of urinary tract infections (UTIs) during the first year of life. However, UTIs are rare and can be treated.
Prevents infections under the foreskin. It also prevents persistent tight foreskin. Both of these problems are uncommon and are usually due to pulling back the foreskin too hard or with dirty hands.
Decreases the risk of getting some sexually transmitted diseases (STDs) later in life Reduces the incidence of HIV by about 40%, genital warts by about 35%, and herpes simplex type 2 by about 30%.
Lowers the risk of cancer of the penis. However, good hygiene offers equal protection against this very rare cancer.
Keeps your son's appearance "like other boys" or "like his dad." Boys may not mind looking different from other men in their family. However, they do mind being harassed in the locker room or shower about their foreskin. This could happen if most of their buddies are circumcised.
WHAT ARE THE CONS?
Some of the reasons not to circumcise include:
Problems with surgery. Problems that may occur are skin or bloodstream infections, bleeding, and various surgical accidents. One study showed that 1 of every 500 circumcised newborns suffered a serious side effect.
Pain. The procedure causes some pain. However, the doctor can use a local anesthetic around the area to block the pain.
Cost. You may have to pay for the surgery yourself because many insurance companies do not cover the cost.
You must decide quickly. If you initially decide not to have your son circumcised, and then change your mind after your son is 2 months old, the procedure will require a general anesthesia. So try to make your final decision during the first month of life.
