What is the relationship between tumor differentiation and malignancy?

Tumor differentiation is intrinsically linked to its malignancy. Generally, the lower the degree of differentiation in a tumor, the higher its malignancy tends to be, and vice versa. The differentiation of a tumor refers to how closely tumor cells resemble normal cells. Well-differentiated tumors have cells that are morphologically and structurally similar to normal cells, grow slowly, and are relatively less aggressive. These tumors usually respond well to treatment and have a better prognosis for patients. In contrast, poorly differentiated tumors have cells that are markedly different from normal cells, with abnormal shapes and disorganized structures. They grow rapidly and... Learn more

Main Symptoms of Carotid Body Tumor

A carotid body tumor is a rare, slow-growing mass that sits at the fork of the carotid artery in the neck. It starts silent, but as it enlarges it pushes on nearby nerves and vessels, sending clear signals. Neck lump is the star. You feel a painless, rubbery mass just below the jaw that moves up when you swallow but not side to side. Pulsing sensation follows. The lump throbs in rhythm with your heartbeat, especially when you lie flat. Hoarseness or voice change appears if the tumor presses on the nerve to the voice box. Swallowing can catch. Food...

Main Symptoms of Thymoma

A thymoma is a tumor that starts in the thymus, a small gland behind the breastbone. It grows slowly, so symptoms can be vague until it presses on nearby structures or triggers immune problems. Chest pressure is the first clue. You feel a tight, heavy weight behind the breastbone, especially when lying flat. Cough that won’t quit shows up next. It’s dry and hacking, caused by the tumor pressing on the windpipe. Shortness of breath creeps in. You puff on stairs or can’t finish a sentence without pausing. Fatigue is common. Muscles feel heavy, and you need naps even after... Learn more

Main Symptoms of Rectal Adenoma

Rectal adenomas are benign growths inside the rectum that can turn cancerous over time. Because they sit low in the bowel, changes show up early and are easy to spot. Painless bleeding is the classic sign. Bright-red blood drips into the bowl or shows on the toilet paper after you wipe. Mucus coating is common. Stool looks shiny or slimy, as though it’s been wrapped in clear jelly. Bowel habit changes. You may feel the urge to go again right after finishing, or have looser stools than usual. Itching or leakage occurs. The adenoma leaks mucus, irritating the skin around... Learn more

Main Symptoms of Ureteral Tumor

A ureteral tumor is a rare growth inside the thin tube that carries urine from kidney to bladder. Because the tube is narrow, even a small tumor acts like a cork, so symptoms start early and build fast. Painless blood is the hallmark. Urine turns pink, rust-brown, or contains small clots—often on and off, so many blame a simple infection. Flank pain creeps in. A dull, steady ache below the ribs can throb more as the bladder fills and ease right after you pee. Urgency and frequency climb. You dash every hour, yet only a small amount comes out each...
