What cancers cause weight gain?
Certain types of cancer can cause weight gain. Ovarian and colorectal cancer, for example, may cause fluid buildup in the legs or abdomen. This type of edema is called ascites.
Slight increases in weight during cancer treatment are usually not a problem. But if you gain too much weight, it can affect your health. Weight gain is more common with some cancers and some treatments than others. For instance, more than half of people with breast cancer gain weight during their treatment.
More than 684,000 obesity-associated cancers occur in the United States each year, including more than 210,000 among men and 470,000 among women. Breast cancer after menopause is the most common obesity-associated cancer among women. Colorectal cancer is the most common obesity-associated cancer among men.
In some cases, underlying medical conditions may contribute to weight gain. These include: an underactive thyroid gland (hypothyroidism) – where your thyroid gland does not produce enough hormones. Cushing's syndrome – a rare disorder that causes the over-production of steroid hormones.
Weight loss is common among people with cancer. It may be the first visible sign of the disease. In fact, 40% of people say they had unexplained weight loss when they were first diagnosed with cancer. Weight loss associated with cancer may be different than other types of weight loss.
Weight gain and short-term fluctuations may happen for a variety of reasons, such as aging or making lifestyle and dietary changes. However, fast weight gain can be a sign of an underlying health condition, such as a problem with the thyroid, kidneys, or heart.
Weight gain associated with ovarian cancer can occur for a number of reasons, such as: Reduced activity - Some cancer patients experience fatigue and a general lack of energy, which can lead to a reduction in physical activity that can promote weight gain.
Aside from leukemia, most cancers cannot be detected in routine blood work, such as a CBC test. However, specific blood tests are designed to identify tumor markers, which are chemicals and proteins that may be found in the blood in higher quantities than normal when cancer is present.
Several studies reported that weight gain after diagnosis is common among CRC patients [1–3, 10, 11]. All these studies showed that weight gain after diagnosis was more common than weight loss after diagnosis [1–3, 10, 11].
A vitamin D deficiency may also contribute to unintentional weight gain. Chances are you're familiar with vitamin D's effects on bone health. Higher levels of the vitamin can help your body support strong skeletal functions, while lower levels can lead to conditions like osteoporosis.
Why am I so tired and gaining weight?
Unexplained weight gain and fatigue are common symptoms of many underlying health conditions. They can be caused by hormones, sleep problems, mental health issues, and other health concerns. Medications can also cause weight gain and fatigue. Dealing with unexplained weight gain and fatigue can be difficult.
Weight gain and cancer
Weight gain is also common and may be unexpected. However, it can happen before, during and after cancer treatment.

Signs of Pancreatic Cancer. Dr. Cohen explains, "Pancreatic cancer symptoms include weight loss, increased blood sugar, epigastric pain, jaundice, and nausea."
Since many people can't eat enough in a day or two to actually gain 5 or 10 pounds, if you notice a dramatic increase on the scale, chances are it's due to water, says Anita Petruzzelli, M.D., owner and medical director of BodyLogicMD.
Weight gain can be extremely frustrating, especially when you don't know what's causing it. While diet typically plays the largest role in weight gain, other factors — such as stress and lack of sleep — may contribute as well.
Stress from eating less causes high levels of cortisol [stress hormone] which has a direct affect on causing belly fat gain. Other factors like what and when you eat can also results in belly fat gain. Disruption in sleep and overall less sleep causes increase in ghrelin levels.
Certain types of cancer can cause weight gain. Ovarian and colorectal cancer, for example, may cause fluid buildup in the legs or abdomen. This type of edema is called ascites.
Some children with acute lymphoblastic leukemia (ALL) may become overweight. They are at most risk of gaining weight during their treatment and up to one year after finishing it. Encourage your child to adopt healthy eating habits and be physically active.
Because pancreatic cancer progresses rapidly, and no method of early detection is currently available, it's one of the most dangerous types of cancer. The incidence rate has increased by about 1% per year since 2000. The five-year survival rate sits at only 11%.
Does stomach cancer cause weight gain?
"ascites" refers to fluid buildup in the abdomen. This may present as weight gain (especially around the abdomen), shortness of breath, sense of bloating, nausea, vomiting or indigestion.
The 3 main symptoms of bowel cancer are blood in the stools (faeces), a change in bowel habit, such as more frequent, looser stools, and abdominal (tummy) pain. However, these symptoms are very common.
You can have ovarian cancer but have few or no symptoms in the early stages. One of the warning signs that you may overlook is weight gain. The extra pounds are both a risk factor for getting ovarian cancer as well as a side effect from the disease or its treatments.
Colon cancer can cause changes in the color, consistency, and frequency of your poop. These changes can include blood in the stool, narrow stools, more frequent bowel movements, and diarrhea. In advanced stages, poop may become black and tarry.
Overweight and Obesity
In the United States, 20% of young people aged 2 to 19 years and 42% of adults have obesity, which can put them at risk of heart disease, type 2 diabetes, and some cancers.
