Is any of this happening?
Be seen today
Contact your treatment team promptly for new black stools, mild bleeding, worsening pain, repeated vomiting, increasing abdominal swelling, or side effects that make it hard to eat, drink, or take medicine.
These symptoms may indicate major bleeding, obstruction, perforation, or another urgent problem.

Does any of this apply?
Book an appointment
Arrange a routine appointment for ongoing abdominal discomfort, unexplained early fullness, persistent nausea, unplanned weight loss, unusual tiredness, or a lasting change in bowel habits.
These symptoms are often caused by other conditions, but persistent changes need assessment.
Report new symptoms during follow-up rather than waiting for the next scan.
Every sign above is quoted from the sofidex article on Gastrointestinal stromal tumors. If you are not sure, err upward — it is always reasonable to be checked.
