Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer.
To prevent new cancers from starting, scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective...
Assessment checks the nutritional health of the patient and helps to decide if nutrition therapy is needed to correct a problem.
Screening and assessment may include questions about the following:
Weight changes over the past year.
Changes in the amount and type of food eaten compared to what is usual for the patient.
Problems that have affected eating, such as loss of appetite, nausea, vomiting, diarrhea, constipation, mouth sores, dry mouth, changes in taste and smell, or pain.
Ability to walk and do other activities of daily living (dressing, getting into or out of a bed or chair, taking a bath or shower, and using the toilet).
A physical exam is also done to check the body for general health and signs of disease. The doctor will look for loss of weight, fat, and muscle, and for fluid buildup in the body.
Finding and treating nutrition problems early may improve the patient's prognosis (chance of recovery).
Early nutrition screening and assessment help find problems that may affect how well the patient's body can deal with the effects of cancer treatment. Patients who are underweight or malnourished may not be able to get through treatment as well as a well-nourished patient. Finding and treating nutrition problems early can help the patient gain weight or prevent weight loss, decrease problems with the treatment, and help recovery.
