Sorry it is taking so long to get in to see a dermatologist. Are you in the USA? My dermatologist is much easier to get an appointment with than to have to wait a month.
Well it is almost May, and It seem you have no other choice than to protect the skin from sun light until you doctor can give you specific diangostics and advice.
Take care of yourself, being a mother is a very important role and one pray and believe you will continue to do a great job at. Make sure your children use sun screen when they are "at the beach" or anywhere else that they have prolonged exposure to sun, anything exposure over 15 minutes should be avoided unless a SPF of 30 or so is on the skin.
I don't do so well in this regard myself and I continue to have some concern about rough off-colored skin on my cheek just below the left eye. My dermatologist has looked at it and treated it a couple of times over the last two years.... and yet just today I was outside working in the yard without a hat or sun screen... I corrected both errors after about 30 minutes when it finally occured to me I was getting too much sun on my face.
But, I'm an old guy and a father of grown children... both older than you. Take care of yourself.
Actually I was in the sun from 6-18 years without knowing about skin cancer. Now that I'm 27 the past is daunting on me. I do not smoke but I'm just scared of this appts. Because I have a bad feeling that it is cancer. And I'm young a career women with two kids. I'm worried its stage 4 or 5 since its been so long the spots have been there and have changed.
I hope you now have the message, the sun can, and will damage unprotected human skin.
Given a history of cancer it seems to me you would know to be careful. I do not know the cervical cancer means you are more prone to skin cancer, but it suggest to me you need to avoid all things that can stimulate cancer - hope you don't smoke or are in frequent company of anyone who does smoke in your presence.
You say you have an appointment with a dermatologist, right? That's the right path forward - can't go back and correct a past mistake.
