Some of the symptoms when to see a doctor after you notice an abnormal growth.
If you're over 30 years old and a new mole appears, see your doctor. These signs and symptoms may indicate a medical concern if the growth is:
Itching or burning
Oozing or bleeding
Asymmetry, when one half of the mole looks different
Suddenly different in size, shape, color or elevation, especially if part or all of the mole turns black
Since you have some of those symptoms, I would recommend you to see a doctor as early as you can especially as the mole is increasing in size and bleeds occasionally. Have your doctor perform the physical examination and also a biopsy
to rule out other conditions and conform the diagnosis
Your family doctor can usually let you know if it's normal or needs further investigation. He or she may then refer you to a specialist.
Thanks and hope this helps.
