Cancer is mostly found in people over the age of 55. 80% of all cases diagnosed this year were patients over 55.

The human body is composed of trillions of cells. Each cell in our body has a unique responsibility from giving our body structure, to absorbing food, and converting food to energy. Just as each cell has a unique job, they also have unique left spans. In fact, the average adult male has over 96 million cells die on him every minute. In order to continue on cells must make copies of themselves to basically replace themselves. Sometimes the process of making copies of cells goes haywire. Some cell will continue to grow and grow and not die when they are expected to. Not only that, these cells that are created do not do the jobs they were expected to do, so they serve no purpose. This can grow out of control and create clumps of cells called tumors. Tumors can often attack other healthy cells around them and in affect cause a lot of harm.

Cancer is not a common cold. It is not contagious. Which means you can't catch it by coming in contact with someone who has it. It is not caused directly by bacteria or viruses. Cancer is caused at the genetic level after a series of changes have impacted the genes, cancer carries on. Your chances of getting cancer are based on your family history and the environment around you. If you have a family member that has had cancer, you are more likely to get it in your lifetime. To stay healthier scientists suggest staying away from UV light and not using tobacco or alcohol. The series of worksheets below will help you learn more about cancer. These worksheets offer a wide selection of how this disease and its abnormal cell growth can directly and indirectly impact the lives of those diagnosed with it and their loved ones. We look at the biology of the disease, the treatments, the progression, and the future of it. We look at how to significantly reduce your risk of having to ever deal with this in your life.

What is It?

Cancers can occur anywhere in the body.

What is It? Questions

Cancer is treated by trying to remove or kill the abnormal cells without damaging healthy cells in the area.


Using chemicals to try to kill these abnormal cells began in the 1940s with the use of nitrogen mustard. Many new chemotherapy drugs have been developed and tested since.

QUESTIONS: Chemotherapy

Chemotherapy is used to cure specific cancers, to control tumor growth, to reduce tumors prior to other treatments like surgery or radiation therapy, to relieve pain or other symptoms, and to destroy those dangerous cells that may still be present in the body after the surgical removal of a tumor.

Food and Cancer Risk

There is some evidence that fruits and vegetables and the nutrients they contain can reduce a person's risk of developing certain types of cancer.


On the other hand, obesity, and the foods generally understood to cause obesity sugar-sweetened beverages, fast food, and processed foods-are linked to a higher risk of many cancers.

Risks with Alcohol

Alcohol use is one of the few things that can be definitively linked to an increased risk of cancer. The type of alcohol (beer, wine, or liquor) does not affect risk.

QUESTIONS: Risky Alcohol

One theory is that the risk has to do with two chemicals which can damage the DNA in healthy cells: ethanol, which is contained in alcoholic beverages, and acetaldehyde, which is formed in the body as alcohol is digested.

Stages of Cancer

Cancer occurs when old cells, which normally die, instead grow uncontrollably and form new, abnormal cells. When these unneeded abnormal cells clump together in a mass, it is called a tumor. It can occur anywhere in the body.


Cancer stage grouping is the result of a combination of primary variables which are collectively known as the TNM system.

Obesity Risks

Obesity is the state of having too much body fat relative to lean body tissue. Obesity is typically measured using the BMI scale, which stands for body mass index.

QUESTIONS: Obesity and Cancer Risk

Over two-thirds of American adults are either overweight or obese.

Processed Foods and Risks

Research published in the BMJ, a weekly peer-reviewed medical journal, in February 2019 indicated that for every 10% increase in the amount of mass-produced, processed foods an individual eats, their risk of developing cancer increases by 12%.

QUESTIONS: Processed Foods

Processed foods are foods that have been created by transforming agricultural products from their natural state into another form; for example, using industrial methods to turn corn into high fructose corn syrup or breakfast cereal.

Sugar and Cancer

Many studies have suggested links between the amount of sugar a person eats and diseases like diabetes, heart disease, and mental health.


Today, evidence linking sugar consumption and cancer continues to grow, as fructose has been shown to change cell metabolism and increase the activity of cancer-causing proteins; however, the subject remains extremely controversial.

PI3K and Cancer

PI3K is the most frequently mutated cancer-promoting gene is humans. Since Dr. Cantley’s discovery, it has been identified as playing a role in 80% of cancers.


The thinking behind PI3K drugs is that blocking the enzyme will disrupt the signals that provide cancer with high levels of glucose, but this is not always the case, and not all clinical trials of PI3K-inhibiting drugs have been successful.

History of Cancer

In the 17th and 18th century, many Europeans believed that cancer was contagious (the infectious disease theory).


It was discovered that cancer could be caused by chemicals (called carcinogens), radiation, viruses, and inherited genes, and that most forms were the result of damaged DNA.
