Cancers are a group of chronic and medical diseases characterized by irregular cells growth in the body tissue caused by the change of DNA transcription of healthy cells.
Normal cells have the division of a limited cell cycle compared to a cancerous cell which can grow unlimitedly.
If an invasive tumor is growing too large, it can suppress the nerves and muscles surrounding them, leading persistent pain and other symptoms, depending on the locations.
The exact causes of cancer are unknown. Researchers do not know why people with the same health condition, some are susceptible to the onset of the diseases, while others do not.
However, an unhealthy diet, such as eating processed foods and fast foods and lifestyles such as smoking, overweight, physical inactivity, and excessive alcohol drinking are some of the major causes of cancer.
Truly, according to the article written by the Telegraph, an unhealthy lifestyle is responsible for half of the onset of the cancers. And overweight or obese is a cause of 12 types of cancer.
Other prevalent risk factors of cancer are genetic mutation inherited from the parents, environment toxic chemicals, radiation, virus, hormone imbalance,... and chronic inflammatory diseases.
Besides the general symptoms such as lumps, loss of appetite, fatigue, tiredness, unintended weight loss, patients with cancers also experience some symptoms totally depended to the location, types, and grade of infected tissues and organs,
Cruciferous vegetables are the group of vegetables belonging to the family Brassicaceae, including cauliflower, cabbage, cress, bok choy, broccoli etc.
According to the recent study, indole-3-carbinol (I3C), a substance presented in cruciferous vegetables suppressed the proliferation of different tumor cells, including those isolated from breast, prostate, endometrium, and colon cancers, in vitro.
Dr. Popolo A, the lead author suggested, the effect of the chemical compound in the treatment of various cancers may be attributed to the interference of cancer cell cycle division and expression of a diverse set of genes involved cell differentiation.
Dr. Aggarwal BB and Dr. Ichikawa H. in the additional examination of the function of indole-3-carbinol (I3C) also found that application of the phytochemical also inhibited DNA-carcinogen abducted and new blood vessels involved cancer cell survival formation, suppressed free-radical production, and stimulated 2-hydroxylation of estradiol in the reduction of cell proliferative and estrogenic activity and
Furthermore, indole-3-carbinol and its derivatives not only exerted the anti-cancer effects through restoring original gene formation but also inhibited free radicals production, ... but also interfered with cancer cell cycle division phase to induce apoptosis.
Other chemical compounds found in the cruciferous vegetables, showed to possess potent antitumor and chemopreventive activity are sulforaphane (SFN), an isothiocyanate and Allyl nitrile (3-butenenitrile).
Taking together, there is no doubt, cruciferous vegetables have exhibited anticancer activities, through many aspects.
Intake of cruciferous vegetables regularly is associated with the reduced risk and treatment of various types of cancer.
However, further data collection on large example size and multi-centers studies performed with human consumption of the whole food of cruciferous vegetables during the course of the disease will be necessary to complete the picture of cruciferous vegetables anti-cancer possibilities.
