Cancer Therapies

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancer

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Cancer-Critical Genes II: Tumor Suppressor Genes

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Nutrition in cancer.

Canadian Family Physician Medecin De Famille Canadien

|February 8, 2011

Summary

Family physicians can improve cancer patient outcomes by monitoring nutritional status. Nutritional support, including counseling and feeding, helps patients respond to therapy and avoid complications.

Area of Science:

Oncology
Family Medicine
Nutritional Science

Background:

Malignant disease presents significant challenges for family physicians.
Nutritional status is critical for cancer patient management and treatment response.

Purpose of the Study:

To highlight the importance of nutritional monitoring in cancer care.
To outline strategies for optimizing patient nutrition during treatment.

Main Methods:

Monitoring nutritional state before hospital admission and between treatments.
Providing nutritional counseling using behavior modification techniques.
Symptomatic treatment of controllable side effects.
Utilizing oral or tube feedings for nutritional support.
