What cancers cause rapid weight loss?

My father has lost a lot of weight very quickly in the past few months, and he isn't even trying to diet. I'm quite concerned and heard this can sometimes be a sign of cancer. Which cancers often cause rapid weight loss?

Pancreatic, stomach, and lung cancers can cause rapid weight loss. First, check if there is an appetite loss and consult a physician for a basic health screening.

Gastro cancers can cause weight loss, but don't worry! 🌸 Sometimes it is just high metabolism or stress, so stay positive and consult a doctor.

Uncontrolled diabetes also causes extreme weight loss very quickly. Check your blood sugar levels along with other screenings to rule it out.

Yes, lung and pancreatic cancers are known for this. Getting a complete blood count and thyroid profile is a good starting point.

When my son lost weight rapidly, I panicked thinking the worst. It turned out to be severe malabsorption due to a gut infection, so please get a proper diagnosis first.

Bro, sudden weight loss can happen from crazy stress or thyroid issues too. Don't directly jump to cancer thoughts, get some blood tests done.

My uncle had rapid weight loss due to colon cancer, which we caught on time. Keep a daily track of weight and stool changes, and share it clearly with your doctor.
