Can Cancer Cause Weight Gain? Understanding the Myths and Realities


Cancer is a serious health condition that comes with a wide range of physical and emotional challenges. One of the most common misconceptions about cancer is that it always causes weight loss. While it’s true that some cancer patients experience weight loss due to a variety of factors, such as a loss of appetite or changes in metabolism, others can actually experience weight gain. In this article, we will explore the relationship between cancer and weight gain and offer practical tips, strategies, and resources for patients and survivors to manage their weight and overall health during and after treatment.

Unpacking the Myth: Can Cancer Actually Cause Weight Gain?

The idea that cancer only causes weight loss is a widespread myth that can be harmful for patients who are struggling with unexpected weight gain during treatment. In reality, there are several ways cancer can cause weight gain. Some cancers, such as breast, ovarian, and pancreatic cancer, are known to cause hormonal imbalances that can lead to weight gain. In addition, the metabolic changes that occur in the body as a result of cancer can cause the body to store excess fat, causing weight gain.

The Unexpected Consequences of Cancer Treatments: How Chemo and Radiation Can Lead to Weight Gain

In addition to the cancer itself, many cancer treatments can also lead to weight gain. Chemotherapy and radiation therapy, in particular, can cause changes in appetite and metabolism, leading patients to eat more and burn fewer calories. Steroids, which are commonly prescribed to cancer patients to manage side effects such as nausea and pain, can also cause weight gain.

Is There Anything You Can Do to Prevent Weight Gain During Cancer Treatment?

While some amount of weight gain during cancer treatment may be unavoidable, there are steps patients can take to minimize its effects. Staying active, following a nutrient-dense diet, and managing stress can all help manage weight gain during treatment. Depending on the type of cancer and treatment, different approaches to weight management may be necessary. It’s important for patients to work closely with their healthcare team to develop a personalized plan for managing weight during treatment.

The Emotional Toll of Cancer-Related Weight Gain: Coping Strategies and Support Resources

Cancer-related weight gain can have a significant psychological impact on patients, leading to feelings of depression, anxiety, and negative body image. Coping strategies such as mindfulness practices, support groups, and therapy can all provide emotional support for patients struggling with these emotions. It’s important for patients to prioritize their mental health and seek help if needed during and after treatment.

From Survivor to Thriving: How to Regain Control of Your Health and Fitness After Cancer

After completing cancer treatment, many survivors find themselves struggling to regain their physical health and fitness. However, it’s important to remember that recovery is a gradual process that should be approached holistically. Patients can take steps such as incorporating regular exercise into their routine, following a balanced diet, and cultivating positive self-talk to support their overall wellbeing during their post-treatment journey. Resources such as survivorship programs, nutrition counseling, and fitness classes can all provide support and guidance for survivors seeking to regain control of their health.

Talking to Your Doctor About Cancer-Related Weight Gain: What You Need to Know

Communication with healthcare teams is essential for managing cancer-related weight gain. Patients should feel confident in asking questions and expressing concerns about their weight and overall health during and after cancer treatment. In some cases, medication adjustments or lifestyle changes may be necessary to manage weight gain. Your healthcare provider can provide guidance on the best approaches for managing your weight and overall health during cancer treatment.


While cancer-related weight gain may be unexpected and challenging for patients, it’s important to understand that it is a common issue that can be addressed and managed with the right resources and support. By staying informed, working closely with your healthcare team, and prioritizing physical and mental health, patients and survivors can take control of their weight and overall wellbeing during and after cancer treatment.
