My understanding is that cancer actually damages the human cell:
According to Dr. Otto Heinrich Warburg(Nobel Prize Winner 1931), the cells change from being 'Aerobic'( oxygen fueled ) to become 'Anaerobic'( sugar Fueled )!
As oxygen can no longer be absorbed through the cell, our organs begin to break down and the cancer cells need for sugars, robs our bodies of their nutrients.
Cancer could have a serious effect on human health because it makes the growth in cell number slow down and with out cells you wouldn't be able to live. Cancer also kills your cells which makes things even worse.
Radioactive pollution causes cancer.
Chickenpox can cause serious infection in cancer patients. Cancer patients are malnourished and immunologically compromised.
It leads to mold and mildew, warp wood, and cause serious illness to humans, especially in the respiratory system.
Lymphatic cancer can be very serious because the lymph nodes are throughout the body.
Yes, animals can get cancer just like humans can.
There are many ill effects of pollution, some of them are short term while others are long term. Some examples of how it affects humans include allergic reactions, headaches, bronchitis, lung cancer and heart disease.
They do not have effect on humans whatso ever.
like humans cancer is hereditary
The MOST serious effect would be death.
An aneurysm is caused by a thinning of the arterial wall which causes a ballooning effect. If the aneurysm bursts serious physical harm results.
PCBs have serious poisons which have been shown to cause damage to the reproductive, neurological and immune systems of wildlife and humans and are known to cause cancer so yes they are poisonous.
