Nose bleed frequently - Cancer? Cancer?

It has been 5 months in the month of nov, when I first noticed my nose bleed. Since then I have faced many problems in my nose. I sometimes get rhinitis allergy and starts sneezing. But most frequently I get nose bleed when I clean my nose. I have used liquid parafin to moisturise my nose. In the month of Jan and feb my problem got in peak. Then recently it became stable. But still once in a week or 10 days when I clean my nose, I get very tiny cells of blood from my nose.(all this from right side of nostril) I dont generally get nose blocks but when i lie down I get nose block on right nostril. I dont feel pain or other problem its just this nose bleed which is troubling me. I get less smell from right nostril as compared to left. I recently started applying oil inside my nose that made me push my finger a little deep inside there in right nostril about 1 inch inside i found hard surface which is not there in left side. Can this possibly be early stage of cancer?
