The short answer
Cancer and its treatment can change your body — hair, scars, weight, or how it works — and shake your sense of identity at an age when both are still forming. These feelings are common and valid. Time, support, honest conversation, and connecting with peers can help you adjust and rebuild confidence.

The full explanation.
Why this hits hard for young adults
The teens, 20s, and 30s are often when people are still figuring out who they are — and cancer can disrupt that just as it is happening. Treatment can change how your body looks and works, and being seriously ill can change how you see yourself and your future. Feeling shaken by this is common and understandable, not a sign of vanity or weakness.
Changes you might face
Physical changes can include hair loss, scars, weight changes, fatigue, and changes in how your body works, including sexual function. Emotional changes can include feeling older than your peers, questioning plans, or feeling that cancer has become part of your identity when you would rather it not define you.
Ways to adjust
There is no timetable for adjusting, and it often comes gradually. Some people find it helps to focus on what their body can do, to reclaim activities and appearance in small ways, and to be honest with people they trust about how they feel. Talking with your care team about physical concerns — many of which are treatable — can also help.
Getting support
You do not have to work through this alone. Counselors can help with the emotional side, and connecting with other young adults who have faced cancer can be especially powerful — they understand in a way others may not. If low mood, anxiety, or body-image distress is persistent, reach out to your team; effective support exists.
