Cancer is a class of diseases characterized by abnormal cell growth that begins in the cells on the surface of the inner lining of the tissue of an organ caused by the alternation of cell DNA with unknown nature.
Under normal circumstance, cell growth is a natural process that happens daily to replace millions of dead cells. In some cases, acceleration of cells growth is necessary to prevent further damage to the body organ, such as cut, injure, etc., but after fulfilling their purposes, the growth of cells are back to a normal rate again regulated growth inhibitors.
In other words, healthy cell division is limited to a number of cycles. Compared to normal cells, cells with alternation of DNA or cancer cells can grow indefinitely.
Unfortunately, skin cells sometimes overgrow while healing, leading to scars on the skin.
At the early, most people with cancer are asymptomatic, however, at the latter, due to the size and the tumor, patients may experience general cancer symptoms such as unintended weight loss, fatigue, gastrointestinal discomfort and loss of appetite, and localized symptoms such as severe pain and bleeding.
Cancer can be classified by the types of cells that have become malignant.
* Carcinoma
Carcinoma is a malignant tumor found in anywhere of epithelial tissues lining the cavities, surfaces of structures, and glands.
* Sarcoma
Sarcoma is a type of cancer that arises from malignantly connective tissue cells originated from embryonic germ cells or bone, cartilage, and fat tissues and cells.
* Lymphoma and leukemia
Hematopoietic cells are multipotent stem cells that give rise to all types of the blood cell, including red blood cells, white blood cells, and platelets become cancerous.
* Germ cell tumor
Cancer derived from pluripotent cells. In adults, these are most often found in the testicle and ovary but are more common in babies and young children.
* Blastoma
Blastoma is cancer derived from immature "precursor" or embryonic tissue, mostly in children.
The causes of cancer are not identified. However, the most prevalent factors associated with the cancer onset include age, family history, long-term exposure to certain cancer-induced chemicals, use of tobacco, and excessive alcohol drinking,..... the list goes on and on, depending on the types of cancer.
Some researchers suggested that the most common risk factor that causes cancer in the Western world may be associated with widespread obesity.
Dr. Karen Basen-Engquist, in the evaluation of obesity risk of cancer, said, "In the United States, approximately 85,000 new cancer cases per year are related to obesity. Recent research has found that as the body mass index increases by 5 kg/m2, cancer mortality increases by 10%".And, "High priorities for future research involve additional work on the underlying mechanisms, and trials to examine the effect of lifestyle behavior change and weight loss interventions on cancer and intermediate biomarkers".
The findings strong indicated the risk of cancer is increased substantially in obese.
Cranberry is an evergreen dwarf shrub, genus Vaccinium, belongings to the family Ericaceae, native to Northern America and Southern Asia. Because of its health benefits, cranberry has been cultivated in some parts of the world for commercial profit and used in traditional and herbal medicine to treat wounds, urinary disorders, diarrhea, diabetes, stomach ailments, and liver problems.
On finding a potential compound for the treatment of invasive tumors, researchers examined the potential effects of cranberry on cancer prevention and treatment.
According to the review of the medical literature by searching the database of PubMed, cranberry and/or its components may act as chemopreventive agents, that diminish the parameters associated with the onset of cancer, including the inhibition of cells oxidation and inflammatory-related processes, in vitro.
Cell proliferation and angiogenesis and metastasis involved in cancer cell invasion were also attenuated by the administration of cranberry's apoptotic activity.
Dr. Mantzorou M, the lead scientist, after taking other factors into account wrote, " Cranberry could be considered as a conglomeration of potential effective anticancer drug-like compounds".
Additionally, in chemical constituents analysis, cranberry showed an inhibitory action of against cancers of the esophagus, stomach, colon, bladder, prostate, glioblastoma and lymphoma.
The efficacy of anti-cancer activity was attributed to the chemical compounds works synergistically to result in cellular death induction via apoptosis, necrosis, and autophagy, reduction of cellular proliferation, the elevation of reactive oxygen species, and modification of cytokine and signal transduction pathways, similar to those of aforementioned study.
Taken altogether, cranberry may be considered a remedy for the prevention and treatment of cancer, pending the confirmation of the larger sample size and multicenter human study.
