The American Cancer Society (ACS) issued a report discussing optimal nutrition and physical activity issues during the phases of cancer treatment and regaining living after recovery from treatment, and living with advanced cancer. The glutted report appeared in the September/October issue of CA: A Cancer Journal for Clinicians (http://CAonline.amcancersoc.org/cgi/content/full/53/5/268).

Nutrition and Physical Activity Across Stages of Cancer Survivorship

The image of cancer survival includes treatment and recruiting living after recovery, and living with advanced cancer. Each of these stages has different requirements and challenges in word s of nutrition and physical activity that are influenced by means of the primary site of cancer and therapeutic methods

TREATMENT AND RECOVERY

Surgery chemotherapy, and radiation therapy can affect a cancer patient's digestion, absorption, and use of nutriment which in turn can cause unintentional weight los or gain, and los of muscle mass. customary cancer symptoms and toxic tenors of cancer treatments include anorexia, weight change, fatigue, nausea, vomiting, pain, changes in taste or fragrance and changes in bowel habits.

The mostly important nutritional goal for cancer survivors at risk of unintentional weight los (eg bodily forms who are already undernourished or individuals who receive directed treatment to the alimentary tract) during active cancer treatment is maintaining life balance or preventing weight los If the patient is experiencing early satiety or reduc appetite, eating smaller, more haunt meals may increase food intake. Nutritious snacks or nutrient-dense drinks may be appropriate for ones who cannot meet their nutritional wants through regular diet alone.

The use of dietary vitamin and mineral add tos during cancer treatment remains controversial. Until further evidence is available that moves more benefit than harm, the authors of the report commend that cancer survivors receiving chemotherapy or radiotherapy avoid exceeding the tolerable upper limits of the Dietary concerns Intake for antioxidant vitamins of that kind as vitamins C and E

It is unknown whether exercise during cancer treatment has any meaning on treatment efficacy. Deciding when to initiate physical activity should be based onward the patient's condition and personal choices Patients receiving radiation therapy and chemotherapy should alter their program or begin exercise at a lower intensity and progres at a slower pace compared with bodily substances who are not receiving cancer treatment. Patients who were exercising regularly before diagnosis should make experiment of to maintain levels of activity as often as possible. Patients who were sedentary before diagnosis should adopt low-intensity activities of that kind as short, slow walks and stretching. Special attention should be given to balance and reducing the risk of falls and injuries in older living bodys and those with significant impairments. If the disease or treatment requires increaseed periods of bed rest, then reduc endurance, reduc fitness, and decreased muscle force should be expected. Physical therapy is make acceptableed for these patients.

LIVING AFTER regaining FROM TREATMENT

principally cancer survivors are free of disease or stable after the initial diagnosis and treatment. During this period, it is important to station and achieve lifelong goals for appropriate weight, healthy diet, and a physically active lifestyle. The report praises that following the ACS guidelines in succession diet, nutrition, physical activity, and cancer prevention may help render the risk of cancer return (Table 1).

LIVING WITH ADVANCED CANCER

For patients living with advanced cancer, nutrition and physical activity are vital to establishing and maintaining well-being and quality of life. Many of these patients may ne to adapt rations choices and eating patterns to convenient nutritional needs and to manage symptoms and adverse purports such as pain, constipation, and los of appetite. There is about evidence that medications, such as megestrol acetate, may enhance appetite in these patients. The use of nonsteroidal anti-inflammatory physics or omega-3 fatty acid oral postscripts may stabilize or improve nutritional status, functional status, and visible form [i]or[/i] frame weight.

Physical activity may help increase appetite and relieve constipation. The ACS report commends that the use of tube feedings and total parenteral nutrition be individualized, with clear recognition of the associated risks for complications.

Women who are overweight should keep up modest weight loss (1 to 2 lb [045 to 091 kg] by means of week) provided it is approved according to the treating oncologist, monitored closely and does not interfere with treatment.
