Will underarm hair removal treatment affect a sebaceous gland lump in any way?

My concern is I used to have an armpit lump under one of my armpits, which the doctor claimed it was a sebaceous gland during the time of diagnosis. Now, fast forward to 12 years later, the lump is still there, but it has gotten smaller in size. Whenever I touched it, it feels like there is small pimple (about 0.25 cm) hidden underneath my skin. My question is if I were to go for underarm laser hair removal treatment, will it affect the armpit lump in any way? Thank you.
