A cancer patient's immune system can be compromised in several different ways, including poor nutrition, chemotherapy and surgery. Because the immune system is not a single organ in the body, strengthening it involves a multifaceted approach. In order to fight cancer, your body needs a combination of improved nutrition, increased rest, physical activity and avoidance of stress. This combination will maximize your resistance to illness so that you can focus your resources to fight cancer.
Step 1
Eat a nutritionally sound diet focused on fresh fruits, vegetables, whole grains, lean meats and dairy products. According to Dr. Marisa Weiss, president and founder of Breastcancer.org, individuals receiving chemotherapy for cancer treatment experience a decreased number of white blood cells. In order to replenish the supply, your body needs high-quality nutrition that does not include nutrient-poor processed foods.
Step 2
Learn how to cope with stress effectively. Harvard Medical School explains that chronic exposure to stress can reduce the number of immune or "T" cells produced, making you more susceptible to opportunistic infections. Stress is difficult to avoid, but learning how to respond to stress can change the way it affects your immunity. Practice meditation, deep breathing techniques or behavioral modification using an online course, DVD or a professional in cognitive behavioral modification.
Step 3
Sleep at least eight hours every night. According to MayoClinic.com, sleep deprivation can lead to a compromised immune system; you are more likely, then, to get sick from viruses. Sleep is necessary for the production of cytokines, which are critical in fighting infection and also in regulating sleep. Sleep is a restorative process that your body uses not only to rest, but also to replenish supplies of cells and tissues. Avoid drinking caffeinated beverages in the late afternoon or early evening because they can disrupt your ability to sleep.
Step 4
Seek support from family, friends or support groups. Harvard Medical School explains that several research studies have revealed that social isolation can cause decreased immunity. It's no surprise, then, that nearly every cancer treatment center has a variety of support groups for individuals and family members living with cancer. Isolation often leads to depression, which can also lower immune cell activity.
Step 5
Exercise regularly. Harvard Medical School explains that regular physical activity is the foundation of improved immunity. Exercise also improves mood and energy, which are often negatively affected by cancer and treatments such as chemotherapy. Speak with your doctor about how much and what kind of activity is right for you, based on your current health. Consider exercising with a friend, which can also decrease feelings of isolation and improve immunity to fight cancer.
