What are the symptoms of colon cancer in young adults?

Unlike older adults who may be diagnosed through routine screening, most younger people notice symptoms. These symptoms are often mistaken for less serious conditions, such as stomach upset or hemorrhoids. Because of this, diagnosis is sometimes delayed. It's important to know the signs and talk with a healthcare professional if they don't go away. 

Common symptoms to look for include:

• Rectal bleeding. Almost half of young people with colon cancer have rectal bleeding. Blood in your stool or on toilet paper may be a sign.
• Stomach pain or cramping that doesn't go away.
• Changes in bowel habits, such as new or lasting constipation or diarrhea.
• Feeling very tired or weak, which may be caused by low iron.
• Weight loss without trying.
• Bloating or feeling full soon after eating.
• Nausea or vomiting.

These symptoms are generally consistent for many people with early-onset colon cancer.
