Are breast reduction surgeries, which may cause pain due to excess fat, considered forbidden and self-inflicted killing, leading the perpetrator to abide eternally in Hellfire?

Cosmetic procedures are permissible in certain exceptional cases, such as: if an organ does not perform its function adequately, like crooked teeth preventing food mastication, or strabismus in the eyes, or breast hypertrophy causing persistent or frequent pain, provided that this is done to restore the organ to its original creation or its natural function, and there is no other means of treatment. This is because the general rule for cosmetic procedures that alter human creation is prohibition. These rulings are based on jurisprudential principles such as "hardship begets ease" and "necessities permit the forbidden."
