Indeed, if Breast cancer symptoms are left unnoticed or ignored, then the chances of the infected area spreading to organs of other parts of the body are inevitable. Also to mention the malignant area of the breast will worsen and eventually start to swell, bruise, redden, dimple, or tear the skin.
You can die
Yes, it can if left untreated.
you explode
It depends on what and how debilitating it is
If it leads to 'Diverticulosis', left untreated it can!
Usually, depending on the severity of the cancer, and how early it is detected, the host will die. Melanoma, if left untreated, will almost certainly kill the host. However, basil cell carcinoma and squamous cell carcinoma, in a way, a 50/50 chance of killing the host, depending on the earliest mentioned variables.
If not treated the person can die and infect others as well.
He would be in a bad predicament.
Every year, 250,000 Americans are affected by the second-most common type of skin cancer, Squamous Cell Carcinoma. SCC is a cancer on the skin's outside layer, which if left untreated, can cause severe scarring or even death.
Osteomyelitis, is an infection of the bone, which is difficulty to treat due to low blood flow. Treatment is long (like 4 weeks) and usually via IV antibiotics. If you don't get that treated, bone cancer would be the least of your worry. You'd be more likely to die from the untreated infection sooner than any bone cancer can kill you.
In untreated leukemia, the ability to fight infection decreases because the leukemic cells accumulate and lessen the production of oxygen-carrying red blood cells, blood-clotting cells, and normal white blood cells, which are the main infection fighters. If left untreated, the surplus cancer cells overwhelm the bone marrow, enter the bloodstream, and will eventually invade other parts of the body, such as the lymph nodes, spleen, liver, the brain, and spinal cord. The bad news is, there is no way to prevent leukemia, because scientists have been unable to figure out what causes it. The good news: treatment is highly effective in many cases.
An untreated infection may spread to the lymphatic system (acute lymphangitis ), the lymph nodes (lymphadenitis ), the bloodstream (bacteremia ), or into deeper tissues.
