Dear ladysmith105: During and immediately after radiation therapy, there are certain “creams” that should be used and others that should not. These would be recommended by the radiation oncology staff. Regarding creams to fade darkening, the radiation oncology staff may be best equipped to make a recommendation regarding whether any of these remedies may be helpful or whether you would be wasting your money. I am not aware of any supplements being used for this purpose.
You should discuss the breast reconstruction (fat implants) issues with a breast reconstruction plastic surgeon. Make sure it is someone who is well experienced in reconstruction post cancer removal as this may impact the options that are appropriate. We would defer our recommendation to the plastic surgeon who has examined you and can make appropriate recommendations.
Best wishes
