Solid tumors contain abnormal and heterotypic cells that communicate through tight and gap junctions. In contrast with liquid tumors, as the cells multiply, they form a “mass” called a solid tumor and usually do not contain pockets of fluid, pus, air, or other substances.
Solid tumors can be either non-cancerous (benign), pre-malignant (cells that have the potential to become malignant), or malignant (cancerous).
Solid tumors represent approximatively 90% of adult human cancers. They can develop in many parts of the human body.
