Grows. If you manipulate a keloid it could grow larger or become infected.
Don't!!! Keloids don't like to be messed with! see a plastic surgeon to talk about removal!
Keloid Rx. The safest approach is silicone tape/gel (myscaraway, from walgreens/online), steroid/bleomycin injections immunosuppressant/chemotherapyagent) only in pro hands, electron-beam radiotherapy, almost never excision unless radiotherapy can be guaranteed within 24hr after excision. Be very careful or it will be made worse by cutting it! close follow up for 2yrs+ to monitor for recurrence essential!
Keloid. It can be infected. If you keep picking on it- it can grow bigger. So , stop picking your keloid.
