Early warning signs of cancer
Many cancers are curable – especially if caught early. Here are some of the cancer signs you should watch out for:
* Cancer of the large bowel: change in bowel habits (diarrhoea or constipation), unexplained weight loss, pain, passing blood
* Cancer of the cervix: unexplained bleeding or discharge, pain or bleeding after sex, weight loss
* Cancer of the breast: swelling or lump in breast, bloody discharge from nipple, inverted nipple, enlarged glands in armpit, dimpling of the skin of the breast
* Cancer of the lung: persistent bad cough; blood in sputum, chest pain, wheezing, weight loss
* Cancer of the stomach: weight loss, persistent indigestion, vomiting blood, lump in abdomen, feeling full after very small meals
* Cancer of the liver: pain in abdomen, loss of appetite, weight loss, yellow eyes and skin, abdomen swollen
* Cancer of the ovary: irregular periods, hard lump in abdomen, pain during sex, bowel problems, excessive hair growth, voice gets deeper
* Cancer of the brain: headaches, vomiting, visual disturbances, weakness or paralysis, dizziness, fits, memory loss, personality changes
* Cancer of the skin: skin lesion that doesn't heal, bleeds, gets larger, changes shape, size or colour
* Cancer of the prostate: pain, urine retention, difficulty in passing urine
* Cancer of the testicle: swelling in testicle
* Cancer of the blood (leukaemia): tiredness, paleness, bruising, bleeding easily, lots of infections
* Cancer of the womb: bleeding after sex, lump felt in abdomen
* Cancer of the throat: hoarseness, lump in throat, difficulty in swallowing, swollen glands in neck
Remember:
A patient with cancer may suffer from one, all or none of these symptoms. These symptom lists are not comprehensive. Patients may suffer from one or more of these symptoms without suffering from cancer. If you are at all worried see your doctor as soon as possible for advice.
The top ten known causes of cancer
1. Foods 50%
2. Tobacco 30%
3. Alcohol 3%
4. Radiation 3%
5. Sunshine 2%
6. Occupation 2%
7. Prescribed drugs 2%
8. Pollution 2%
9. Tobacco (passive smoking) 1%
10. Industrial and household products 1%
These figures are based on the available research. I have not included genetic factors or viruses which are known to cause cancer on this table – that is why the total doesn't add up to 100 per cent. The National Academy of Sciences has concluded that ‘cancers of most major sites are influenced by dietary factors’ and reported that researchers found that ‘more than 40 per cent of cancers in men and almost 60 per cent of cancers in women in the United States could be attributed to dietary factors’. It has been estimated that dietary modifications might result in a one third reduction in the number of deaths from cancer in the United States – with a 90 per cent reduction in deaths from cancer of the stomach and large bowel; a 50 per cent reduction in deaths from cancers of the endometrium, gallbladder, pancreas and breast; a 20 per cent reduction in deaths from cancers of the lung, larynx, bladder, cervix, mouth, pharynx and oesophagus and a 10 per cent reduction in deaths from other sites.
Many people who are aware that cancer is caused by environmental factors seem to believe that the causes are outside their control – regarding the pollution of air, water and food with chemicals as being the major risk factors. This table clearly shows that food and tobacco are by far the two most important causes of cancer and that, therefore, most people have far more control over their own risk of developing cancer than they realise. It is widely agreed that 80 per cent of all cancers are preventable – using knowledge which we have available at the moment. In other words ignorance (sustained through political and industrial expediency, supported by a corrupt medical establishment) is responsible for 80 per cent of the millions of deaths caused by cancer each year.
