8. Vomiting or nausea
Bowel cancer may result in nausea, bloating, as well as vomiting if it starts to block the intestinal tract. This symptom is particularly worrying in case it happens together with some other signs.
9. Low Iron Levels

- Radiation: Radiation is often used to reduce tumours in rectal cancers before surgery.
- Targeted treatments: Medications that primarily target cancer cells while not destroying healthy tissue.
Early-stage cancers typically respond better to therapy and tend to be much less aggressive.
