What You Can Do to Help Prevent Cancer
A Third of Cancer Cases Trace Back to Things You Can Change
Almost everyone has watched cancer take someone they cared about. That experience leaves a particular kind of dread, a sense that the disease arrives without warning and without reason, and that nothing a person does makes much difference.
The data argue otherwise. A worldwide analysis published in Nature Medicine examined cancer risk across 185 countries and concluded that more than a third of cancer cases are attributable to modifiable factors, meaning exposures and behaviors that are open to change.
That finding reframes the question. At Prosperity Health in Royal Oak, MI, Dr. Nishath Hakim uses a whole-person functional medicine approach to help patients monitor the systems that govern cellular health, on the understanding that the effort to prevent cancer is an ongoing practice rather than a single test result.
What Causes Cancer Risk
Tobacco remains the single largest contributor worldwide, followed by chronic infections, alcohol consumption, and environmental exposures. Each of these operates through a similar route, imposing sustained stress at the cellular level that produces inflammation, damages DNA, and interferes with the repair machinery meant to correct that damage.
What lies beneath those exposures matters just as much, and receives far less attention. Metabolic health and mitochondrial function determine how well cells generate energy, manage waste, and respond to injury. Two people exposed to the same carcinogen do not carry the same cancer risk, and the difference lies largely in how well their cellular systems are operating.
When energy production falters, when inflammation runs high, and when immune surveillance is impaired, the body becomes less able to identify abnormal cells and correct their behavior. Abnormal cells appear constantly in healthy people, and a functioning system removes them. The capacity to do that reliably is what efforts to prevent cancer are ultimately protecting.
What You Can Do to Prevent Cancer
Dr. Nishath Hakim does not treat cancer prevention as a list of tasks to complete. The objective is to build an internal environment in which the body can produce energy, repair damage, and regulate itself properly, and that objective rests on a handful of foundations.
Prevent Cancer with Nutrition
Steady blood sugar, sufficient protein, and nutrient-dense whole foods support mitochondrial function and reduce inflammatory signaling. Heavily processed foods, excess alcohol, and erratic eating patterns push in the opposite direction, accumulating stress on these systems year after year. Repeated blood sugar spikes and the insulin response they provoke are of particular interest in cancer research, since insulin acts as a growth signal.
Preventing Cancer & Body Composition
Excess body fat is metabolically active tissue rather than inert storage. It secretes inflammatory signals and hormones that influence cellular behavior throughout the body, which is why body composition carries weight in any serious conversation about how to prevent cancer. What matters is the proportion of fat to lean tissue, not the number on a scale.
Prevent Cancer with Movement
Regular activity improves insulin sensitivity, supports mitochondrial function, and lowers systemic inflammation. Extremes are unnecessary, and consistency counts for considerably more than intensity. Muscle tissue also functions as a metabolic organ, absorbing glucose and improving the body’s handling of it. Daily walking combined with strength training a few times each week is among the most effective and most sustainable strategies available to help prevent cancer.
Prevent Cancer with Stress Reduction
Chronic stress is one of the most underestimated contributors to disease. Cortisol elevated over long periods compromises immune function, raises inflammation, and disrupts metabolic control. Supporting the nervous system through adequate sleep, daylight exposure, genuine recovery time, and hormonal balance where appropriate is a legitimate part of any plan to prevent cancer.
Prevent Cancer with Hormonal Balance
Hormones regulate cell growth, immune activity, and metabolic rate, so imbalance in one of these systems affects the others. This becomes especially relevant for women during perimenopause and menopause, when shifting estrogen and progesterone can amplify inflammation, disturb sleep, and alter body composition at the same time. Assessing and addressing hormonal status supports the broader effort to prevent cancer rather than being a separate concern.
Prevent Cancer with Sleep & Circadian Rhythm
Sleep is not negotiable in this context. DNA repair, immune regulation, and the resetting of metabolic pathways all take place during sleep, which means poor sleep sustained over years degrades every one of those functions. Keeping consistent sleep and waking times, limiting light exposure at night, and getting daylight early in the day all reinforce the circadian signals these processes depend on.
Preventing Cancer by Reducing Toxic Load
No one eliminates every exposure, but the largest ones can be reduced substantially. Avoiding tobacco and limiting alcohol account for the greatest share of the benefit, and paying attention to environmental exposures, improving air and water quality where circumstances allow, and choosing cleaner household and personal care products account for much of the remainder.
Small changes made consistently in these areas reduce cumulative exposure meaningfully over a period of years. The value lies in the accumulation rather than in any individual decision, which is a more encouraging prospect than trying to achieve a toxin-free life that no one can actually achieve.
Help Prevent Cancer with Functional Medicine
These foundations reinforce one another, which is the central argument for addressing them together. Poor sleep raises cortisol, elevated cortisol impairs glucose control, impaired glucose control drives inflammation, and inflammation compromises the immune surveillance that removes abnormal cells. Improving one link tends to relieve pressure on the others.
Functional medicine works from that interconnection deliberately. Top Royal Oak, MI internist Dr. Nishath Hakim assesses metabolic markers, inflammatory indicators, hormonal status, nutrient levels, and lifestyle patterns as a single interdependent picture, then builds a plan around what the testing actually shows for that individual.
Improving metabolic health, supporting immune function, optimizing hormones, and reducing chronic stress and inflammation change more than how a person feels this month. They alter the long-term trajectory. None of this offers a guarantee, and appropriate cancer screening remains essential regardless of how well the underlying systems are functioning.

If cancer has touched your family and you have wondered whether anything you do actually matters, the evidence indicates that it does. A substantial share of risk sits within reach of the decisions you make about food, movement, sleep, stress, hormones, and exposures.
Knowing where your own vulnerabilities lie requires testing rather than guesswork. To review your metabolic and hormonal health and build a plan to help prevent cancer over the long term, schedule an appointment with Dr. Nishath Hakim at Prosperity Health.
