Cancer Prognosis
No doctor can be absolutely sure that a patient who attends is going to heal. The odds of a person depend primarily on how early the disease is discovered, but also the type of cancer, as some are more aggressive than others. Another contributing factor is the physical condition of the patient is very important that your fitness is good and the disposition towards the disease, as you must face it and help with your mood cure.
From the decade of 1990 and available treatment techniques, cancer is curable in approximately 50% of patients diagnosed. Cancer prognosis depends mainly on:
• The primary tumor site.
• The histological type with the degree of cell differentiation, their biology and cytogenetics.
• The state of cancer or disease extent.
• The age of the patient.
• The functional status or patient's physiologic reserve.
Recently, studies also suggest psiconeuroimnunología the influence of emotional factors in the course of the disease.
Cancer Prevention
Although the cause of cancer is unknown and multifactorial in many cases elsewhere, are known about risk factors that increase the likelihood of cancer and should be avoided, such as smoking or smoking any other way. It is estimated that up to 50% of cancers could be avoided.
A vaccine against cervical cancer was recently approved. The marketing of this vaccine was approved in several countries and studies the adoption of other vaccines against skin cancer and prostate cancer [citation needed].
Primary prevention
It is cancer screening in asymptomatic individuals, with the aim of reducing morbidity and mortality.
• Education and health habits:
1. Quitting smoking: save and prolong life more than any activity of Public Health. In addition to snuff with nicotine, virtually all smoke that is inhaled carcinogens often has elements (for example, tar is a carcinogen found in various smokable substances).
2. Diet Healthy: in this sense is recommended to be varied, with sufficient amount of nutrients (especially vitamins and elements such as phytosterols, sulfur, selenium and essential fatty acids like Omega 3 and never the omega-6 to be pro-inflammatory and thus favoring tumor development), therefore we recommend the consumption of organic foods including cabbage or cabbage, cauliflower, broccoli or broccoli, fruits rich in vitamin C, pomegranate, tomato, almond, citrus (eg peel tangerine has salvesterol Q40 compound with anticarcinogenic properties) and fiber-rich foods - like whole wheat bread-facilitates intestinal transit and thus the elimination of toxins, so does the consumption of more than one liter of drinking water per day (drinking water must be free or have only very small amounts of arsenic).
A day we now know that omega 3 is aniinflamatorio and the omega 6 is proinflamaorio, and we consume a disproportionate amount of omega 6, mainly by a change in livestock feed that passes along the food chain, and the abuse of vegetable fats and oils in food industry. Soybeans and corn which is fed to livestock is one of the causes of cancer incidence has skyrocketed. No doubt food is one of the fundamental pillars, as the incidence of cancer in heavily contaminated countries like India is much lower than in Western countries. We also know that Asians who emigrate to the United States within 1 or 2 generations have similar proportions of cancer to Americans and not that of Asians (much lower in many types of cancer) The explanation can only be mainly in the food chain, and other causes such as ionizing radiation. It is advisable to take ratios of 4:1 between omega 3 and omega 6. Yet we Westerners ratios of 20:1 or 30:1 in favor of omega 6. I should mention that fatty acids n-6 interfere with the absorption with omega 3, and the only sources of omega 3 that do not contain high proportions of omega-6 are fish and ever, despite the publicity, plants such as soybeans. It is remarkable that the food pyramid recommends only take fish 2 times a week for the pollution of the seas with mercury, highly toxic metal, so it is advisable not to abuse the fish because the beneficial effects of omega 3 would be exceeded by the loss of mercury. In this sense can be interesting supplements of fish oil or krill oil, molecularly distilled for heavy metals discarded. Green tea has proved particularly effective in antitumor treatment, so it should be incorporated into the daily diet, along with other spices like curry with high concentrations in turmeric, and N-acetyl-cysteine, which showed higher levels of one of the most potent antioxidants known, synthesized by our body, glutathione.
Also another important change in diet, besides the aforementioned with fatty acids, like sugar, and in general the monosaccharides added to the industrial food and refreshments. The entry of blood sugar causes the action of insulin and IGF1. Elevated levels of insulin and IGF1 increases the incidence of cancer. So are desirable complex carbohydrates and high in fiber, and has to avoid white bread, soft drinks, burgers, etc, also predispose to cancer and diabetes mellitus, obesity and associated comorbidities. In general, we must change the model of complete feed, and preferably organic feed free of pesticides and livestock fed with excess omega 6. It is also remarkable lack of training of oncologists in food whenever possible to minimize inflammation and stimulate the immune system, it would be desirable to input specialized in oncology nutritionists in the Spanish health.
They are considered very harmful the fast foods especially those with sodium cyclamate or saccharin as "sweeteners" as well as the abundant nitrates (such as with hot dogs), it is convenient too much consumption of sugar, just as are harmful foods contaminated by mycotoxins (eg aflatoxins). Strongly recommended that consumption of olive oil and virgin virgin but is discouraged "olive oil" third raffinate are the harmful hydrogenated fats and trans fats. It discourages the use of oil completely rehash and eating food often partially or totally burned. Carcinogenic compounds also have adverse effects if consumption is chronic, smoked foods. It discourages regular alcohol consumption: there is a certain tolerance of the human body to moderate doses of fermented alcoholic beverages such as wine, the beer or cider but are very predispositivas to various forms of cancer distilled spirits (vodka, whiskey, gin etc.)..
• Excessive consumption of animal fats appears reduction for breast cancers.
With regard to meat consumption, studies of the year 2007 advise against consuming more than 500 g of red meat per week, however, is considered positive fish consumption, particularly of so-called blue fish (like tuna) but contamination water makes the big fish can accumulate in their tissues that would make products harmful long-term toxic. Finally, it is advisable to be healthily thin.
• The low consumption of vegetable fiber slows the activity of the digestive tract causing toxins to accumulate in the intestines, so it is a diet food with natural fibers (cellulose of the segments of citrus, cellulose present in the bread and whole grains, brown rice preparations-grain rice with husks, etc., are almost always beneficial.).
• Avoid prolonged exposure to the sun (or other sources of UV radiation) is almost obvious that everything possible should avoid exposure to other ionizing radiation as are the x-rays and elements radioactive, also observed a risk in the microwave well as in high electromagnetic frequencies that occur near high voltage cables or radio antennae powerful. For a light-skinned person in subtropical latitudes (as in much of Argentina, Australia, Spain, Greece, Italy, Mexico, South America etc..) Sea level exposure time would be recommended daily nonstop 30 minutes after this period it is necessary to use protective against ultraviolet radiation. People with fair skin can tolerate more solar radiation in areas located between latitudes 40 ° (South and North) to polar latitudes ... if there are no ozone holes, please note that solar radiation is also very intense if exceed the 1000 meters and is enhanced by reflection in areas covered with sand, snow, and even water. The more pigmented skin populations are more resistant to the effects of ultraviolet radiation but even so it is always advisable to avoid excessive exposure to sunlight or any source of UV.
1. Avoid prolonged exposure to aircraft causing effects of radiation (this applies for example to light fluorescent and so-called black light without proper filtering).
• The sedentary (mainly the lack of physical activity) and overweight is particularly reducing cancers.
• Addressing common gastrointestinal diseases, bacteria (Helicobacter pylori) that cause gastric ulcer or peptic ulcer produce carcinogenic toxins.
• Monitor the development of moles in particular nevi of colors or oversized polka asymmetric require special caution and suggests exceresis or removal, as far as keratoses and warts is always advisable to ask your doctor, rarely become malignant warts although it should caution especially if they affect genital areas or zones of frequent friction.
• Chemoprevention: The use of certain chemical, natural or synthetic, to reverse, suppress or prevent carcinogenesis before the development of malignancy.
1. Genetic testing: The avoidance of certain carcinogenic chemicals or who do not have the assurance that they cause cancer.
2. Consistent with the previous point, the environment where one lives or works should be as much as possible free of carcinogenic elements like smog, the dioxins, sprays tar, lead, PCBs, asbestos excess ozone, or water contaminated with mercury or arsenic.
• The practices sex must be safe; many STDs can degenerate into cancers (eg, hepatitis C and hepatitis B virus, HPV or genital HIV - AIDS).
• The emotional life affects anti-cancer factors or, conversely, carcinogenic. Anticancerigen when the mood of the individual is happy or happiness (often facilitated by physical activity, leisure and entertainment or even for good sleep or the mere possibility of seeing daylight, "as long as there is no excessive sun exposure and even less in the eye) or carcinogens when the emotional state (usually anxiety) lower capacity of the immune system, among which are found mainly to the depression (in particular the derivative of the duels ) and the stress, but above all the fear of death (thanatophobia) or with a tendency to hypochondria.
• Vaccination: The vaccine for certain viruses, may prevent certain cancers. For example, the universal vaccination against hepatitis B, can reduce the incidence of hepatoma.
• It was observed that a chronic shortage of vitamin D predisposes humans to be affected by various cancers.
