"Solid tumors" refer to abnormal growths or masses of cells, forming a cluster or lump that can be felt or seen. Unlike liquid tumors or cancers that affect the blood and lymphatic systems, solid tumors develop in various organs or tissues in the body, such as the brain, lung, breast, or colon. These tumors can be benign (non-cancerous) or malignant (cancerous), with the latter having the potential to spread to other parts of the body.
