Scirrhous carcinomas are characterized by hard, fibrous tumors consisting of rare malignant cells surrounded by dense connective stromal tissue.
Which is a description of Scirrhous type Tumours?
A rare type of stomach cancer that begins in the lining of the stomach and spreads to the muscles of the stomach wall. This causes the wall of the stomach to become thick, hard, and rubbery, which leads to trouble digesting food.
Which is the description of a Fungating tumor?
What are fungating tumors? Often referred to as ulcerated cancer wounds, fungating tumors are tumors that grow to the point that they break through the skin. The growth of cancer beneath the skin blocks blood vessels and oxygen supply to the affected area, ultimately causing the infection and ulceration.
Which is a definition of radioresistant tumor?
Clinically, a tumor is considered radioresistant when irradiation is unable to reduce its volume or when a recurrence occurs after a possible regression. However, tumors with histological characteristics identical to a radioresistant tumor can be highly responsive to radiotherapy treatment.
Which term describes malignant tumors?
Another term for cancer is “malignant tumor.” Tumor literally means “swelling” or “mass.” In this case, it refers to a mass of non-structured new cells, which have no known purpose in the physiological function of the body.
What is a description of Exenteration?
[ ĕk-sĕn′tə-rā′shən ] n. The surgical removal of internal organs and tissues, usually the radical removal of the contents of a body cavity. evisceration.
What is Scirrhous carcinoma of breast?
Scirrhous carcinoma of the breast is a pathological subtype of breast cancer. It is a subtype of invasive ductal carcinoma not otherwise specified and presents as a hard lump.
What does an ulcerating tumor look like?
An ulcerating tumour can start as a shiny, red lump on the skin. If the lump breaks down, it will look like a sore. The wound will often get bigger without any treatment. It can spread into surrounding skin or grow deeper into the skin and form holes.
What is an ulcerating tumor?
Ulcerating cancers are sometimes called fungating cancers (tumours) or wounds. Fungating describes what the cancer might look like. They can grow in the shape of a fungus or cauliflower. These wounds start when a tumour growing under the skin breaks through the skin’s surface.
What is the meaning of fungating?
: to assume a fungal form or grow rapidly like a fungus a bulky fungating lesion— R. F. Thoeni.
Which is radioresistant?
Medical Definition of radioresistant
: resistant to the effects of radiant energy radioresistant cancer cells — compare radiosensitive.
What are radioresistant cells?
Radioresistance is a process in which the tumor cells or tissues adapt to the radiotherapy-induced changes and develop resistance to the IR. This is a complex process involving multiple genes, factors, and mechanisms [34, 35].
What tissues are radioresistant?
The radioresistant tissues, heart, liver, lung and kidney, contain 2 to 15 times more protein per cell, nucleus and chromatin compared with the radiosensitive tissues, spleen and thymus.
