Does any of this apply?
Book an appointment
If you are receiving treatment, use the contact instructions provided by your team rather than waiting for the next routine appointment.
Routine follow-up is the right place to discuss stable symptoms, scan results, treatment choices, side effects that are already controlled, and support with daily activities.
And for anyone, someone who:
has noticed a lump, a mole that has changed, or unexplained weight loss
Every sign above is quoted from the sofidex article on Stage 4 lung cancer. If you are not sure, err upward — it is always reasonable to be checked.
