Keloids are not contagious and can be treated with various methods. Treatment options may include steroid injections, laser therapy, cryotherapy, pressure therapy, and surgery. Depending on the size and severity of the scar, some treatments may be more effective than others. With treatment, the scar can be minimized and the appearance improved. However, the treatment may need to be continued for an extended period of time to see the desired results, and in some cases, the scar may not be completely cured.
