"Sex change surgery" includes the removal of the breasts for female-to-male trans men. For trans women, it includes the removal of the testes and the surgical conversion of the penis into a vagina.
What did Christ Himself say about the removal of healthy body parts? In Matthew 5, Christ tells us:
29 If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. 30 And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell.
If a transsexual is tempted to suicide, a grave sin, and removing a body part would relieve that temptation, then it is clearly permitted by Christ.
Now lets look at the Catechism on the matter:
2297 "...Except when performed for strictly therapeutic medical reasons, directly intended amputations, mutilations, and sterilizations performed on innocent persons are against the moral law."
Although it is by not a perfect "cure," "sex change surgery" is well recognized as a legitimate medical therapy for transsexuals. Therefore, according to the Catechism, sex change surgery is permitted.
Catholics should support transsexuals in bearing their cross. If a transsexual individual commits the grave sin of suicide due to mocking or insensitivity, then those who mocked or were insensitive have contributed to that sin.
1868 Sin is a personal act. Moreover, we have a responsibility for the sins committed by others when we cooperate in them:
If "sex change surgery" will help a transsexual avoid the sin of suicide, we are obligated to encourage her to follow Christ's teachings in Matthew 5 in a compassionate and charitable way.
Almost no one these days fully understands the gravity of such an act and as such it wouldn't be mortal sin for them, hence why the CHurch now allows burials and masses for people who committed suicide.
