Cancer & Physical Activity

Overview
Cancer is a group of conditions where the body's cells begin to grow and reproduce in an uncontrollable way. These cells can then invade and destroy healthy tissue, including organs. Cancer sometimes begins in one part of the body before spreading to other parts. This process is known as metastasis.
 
Around 298,000 new cases of cancer are diagnosed each year in the UK. More than one in three people will develop some form of cancer during their lifetime.1 Data suggests that increased levels of physical activity are associated with lower rates of colon and breast cancer3 but this article is focussed on the use of physical activity and exercise with those individuals that have been diagnosed with cancer.
 
Management and Medication
Treatment options for cancer can include surgery, radiation, chemotherapy, and immunotherapy
 
Effects on Exercise Response
Individuals with, or recovering from, cancer can have physical limitations that result from the disease itself and/or the treatment for the disease. The effect that the disease has on the body is directly related to the tissues affected, for example, shortness of breath may be experienced with lung disease, or anaemia may be experienced if the bone marrow is affected.
 
The side effects of treatments can also be varied and whilst some may be an acute effect that resolves itself once treatment has ended, other side effects may occur later in the treatment process and could be permanent. Scar tissue can result in impaired cardiac, pulmonary or musculoskeletal function with pain or loss of flexibility being experienced long after the cancer has been treated.
 
Benefits of Exercise Training
Studies have shown that regular, moderate-intensity aerobic exercise during cancer therapy results in reduced levels of fatigue, greater body satisfaction, maintenance of body weight.
 
Exercise Recommendations2
  • Aerobic - the goal is to improve & maintain work capacity, control body weight, improve mood, reduce fatigue and improve the Quality of Life. Individuals should aim to complete 20-60min sessions, 3-5 days/week at a symptom limited, moderate intensity of 40%-60% of HRR.
  • Strength - the goal is to maintain or improve strength and increase maximal voluntary contraction. Stregnth exercise should be carried out 2-3 days/week for 20-30min, at 40-60% of 1RM 1-3 sets of 3-5 reps should be gradually increased to 8-15 reps although theintensity should be limited by symptoms.
  • Flexibility - The goal is to increase/maintain ROM and to decrease stiffness resulting from lack of use. Flexibility exercises should be carried out 5-7 days/week with 2-4 reps/stretch holding each stretch for 20-30s.
  • Functional - In order to improve gait and balance, return to work and maintain functional independence individuals should perform exercises that replicate functional activities (ie sitting, reaching, stepping). These should be performed daily.
Other considerations are that an instructor should assess a client's medical condition, functional ability and general health prior to each exercise sessions. There should also be an awareness of where the client is in the treatment schedule and the implications of this to allow for adjustment of the exercise programme where required.
 
Contraindications
Whilst all cancer patients and survivors are subject to the regular list of absolute and relative contraindications to exercise, there are a number of measures and signs that suggest an individuals exercise routine should be curtailed or adapted.
  • Heamoglobin Level < 8.0 g/dL - This can imply that the exerciser has anemia and a reduced oxygen carrying capacity. Instructors should take note of raised heart rates, arrythmias, rapid or difficult breathing, extreme fatigue and high blood pressure. If this is suspected then high intensity exercises should be avoided.
  • Absolute neutrophil count <0.5 x 109/microlitres - This implies that the client may have a low white blood cell count and may be more susceptible to infection. If the client has any blood values taken then they should be encouraged to pass them on to their instructor and if this is identified then the risk of bacterial infection should be minimised. This could be achieved by reducing group sizes, restricting those with contagious conditions and by maintaining high standards of hygiene at all times.
  • Platelet count <50 x 109/microlitres - This could suggest that the client has thrombocytopenia and will bruise easily. If this is noted then the programme should be adapted to avoid activities with an increased risk of bleeding, eg heavy lifting, especially eccentric exercises and high impact sports.
  • Fever>38C (100.4F) - This may indicate a systemic infection or pulmonary toxicity. It may be accompanied by increased breathing rate, and heart rate and feeling cold. Clients should avoid high intensity exercise if noted.
  • Ataxia, dizziness, or peripheral sensry neuropathy - Those with gait problems may be at an increased risk of falls whilst exercising. This could be preceded oraccompanied by confusion, memory loss, seizures, loss of sensation, blurred vision, foot drop, muscle weakness an balance problems. Activities that require a keen sense of balance should ba avoided, although safely developing a sense of balance would be beneficial to the client. Exercise instructions should be kept clear and may need to be repeated at intervals.
  • Severe cachexia (loss of >35% premorbid weight - Those that have undergone a significant loss of weight should avoid high intensity exercise.
  • Dyspnea - Shortness of breathe may indicate pulmonary toxicity and exercise should only be completed to the individuals level of tolerance.
  • Bone Pain -  Exercisers with bone pain should avoid activities that increase the risk of fracture eg high impact sports, spinal flexion, and end-ROM movements.
  • Severe Nausea - This may result from a change in intestinal mucosa, and a subsequent change in intestinal absorption. This may in turn result in malnutrition and a limited capacity to exercise. The client should only be encouraged to exercise within their levelof tolerance and encouraged to seek medical help.
  • Extreme Fatigue and/or muscle weakness - individuals should be encouraged to only exercise within the boundaries of their own tolerance.
