Regret not circumcising my son

When my son was born my husband and I decided not to have him circumcised. I didn’t feel like I knew enough about it to go through with that procedure so I left it the way it was. Now he is 3 months old and I am reading some very scary article saying that uncircumcised males are at a greater risk for penile cancer and STDs! I don’t feel comfortable circumcising him this late as it would be too painful for him. Did i make the wrong decision and will my child suffer for it?
