Cancer occurs when one or more of our cells begin to act independently; it starts to grow and grow out of alignment with the needs of the greater body. It's as if they no longer hear or obey the needs of the body and rest off to have their own survival, even though this can direct to the death of the body and therefore their own end. Cells don't really have much imagination, when they set off for an autonomous existence all that know to do is to grow, develop, reproduce and so this is what they do, some cancer cells will also maintain to execute their dedicated roles as they spread and reproduce e.g. cells from the testis, when cancerous, can produce high levels of oestrogen throughout the body.

Lung (Including Bronchus)
Melanoma
Non-Hodgkin Lymphoma
Pancreatic
Prostate
Skin (Nonmelanoma)
Why Are Many People Getting Cancer?
There are many hypothesis about why people get cancer individually, they are genetic mutations, environmental carcinogens, improper diat and the use of cell phones and electromagnetic equipment. First of all, how much do we suffer from cancer? The statistic that is often cited, especially by people promoting alternative cancer cures, is that 1 in 3 people suffer from cancer at some time in their life.This is unbelievably high.
Common Cancer Symptoms
Although cancers differ to a great extent, there are a few cancer symptoms that are commonly experienced by most cancer patients.
1.Persistent Fatigue
2.Unintentional Weight loss

Skin Cancer Symptoms
Skin cancer is one of the most preventable types of cancer. Skin cancer can be divided into three different types of cancer.
Squamous Cell Carcinoma

Blood in the urine: The presence of blood in urine, is called hematuria. Blood can either be seen by the eye, in which it is called gross hematuria. Blood can also be seen under a microscope, and it is then called microscopic hematuria.
Pain during urination: Pain during urination is called dysuria. Pain can range from mild to severe.
Frequent urination: Having to urinate often and during the night is also a symptom.
We are dying of cancer at an frightening rate, I suggest that unless we learn from our mistakes and start acting in association with life itself by striving to make sure that every action we take is for the betterment of the whole then cancer will continue to act to reduce our population. Like our bodies, Gaia has inbuilt systems to maintain health, if we threaten those systems then they will act to curb our growth, (increased death through disease, source depletion and natural disasters). If we conquer those systems then we will die with the planet.
