Your question: What is the definition of a radioresistant tumor?

What is the spread of malignant tumors to a distant location?

Metastasis is the process by which cancer cells spread to distant locations in the body. The majority of death associated with cancer is due to the metastasis of the original tumor cells.

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 an example of a malignant tumor derived from epithelial tissue?

Carcinomas, malignancies of epithelial tissue, account for 80 to 90 percent of all cancer cases.

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.

THIS MEANING:  Your question: Does dialysis increase cancer risk?

What is the grade of a tumor?

Tumor grade is the description of a tumor based on how abnormal the tumor cells and the tumor tissue look under a microscope. It is an indicator of how quickly a tumor is likely to grow and spread.

What does an ulcerated 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.

Why do fungating wounds smell?

Odour from wounds results from bacteria that reside in necrotic wound tissue. Odour associated with malignant fungating wounds can be upsetting and may contribute to the suffering of the patient and the family. Fungating wounds also present challenging management issues for health care providers.

What happens if a tumor bursts?

When ruptured, the tumor releases a large number of electrolytes, including intracellular potassium, phosphate, and nucleic acid metabolites, all of which may enter systemic circulation and cause a number of life-threatening conditions including cardiac arrhythmia, seizure, and acute renal failure.

What are tumor types?

Tumors may be either benign (noncancerous) or malignant (cancerous). Benign tumors usually grow in one place and do not spread. Malignant tumors develop in one area of the body, then spread to others. Both benign and malignant tumors vary in size.

Which one of the four basic tissue types gives rise to most cancers?

Epithelial tissue is also the most common site for the development cancers. Carcinomas arise from epithelial tissue and account for as many as 90 percent of all human cancers.

THIS MEANING:  Quick Answer: What is the difference between sarcoma and melanoma?

What are examples of benign tumors?

Benign tumors are unlikely to recur once removed. Common examples of benign tumors are fibroids in the uterus and lipomas in the skin. Specific types of benign tumors can turn into malignant tumors. These are monitored closely and may require surgical removal.

What are five characteristics of malignant tumors?

The malignant cell is characterized by: acceleration of the cell cycle; genomic alterations; invasive growth; increased cell mobility; chemotaxis; changes in the cellular surface; secretion of lytic factors, etc.

What is the term for first malignant tumor to appear in the body?

Carcinoma is a malignancy that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a malignancy that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.
