4. A weird lump
If you find a lump in your body or are just noticing a thickening or “change”, this could be an indicator that everything is not as it should be.
Even though some changes in your body are normal, pay close attention and trust your gut instinct.
5. Frequent fever
Cancer affects the immune system which results in a regular fever for what seems like no reason at all.
It’s more common during later stages of some cancers but it shows up early in cancers of the blood including lymphoma and leukemia.
