Is it worthwhile to be on constant vigilance for any symptoms which might indicate cancer has come back ?

Unfortunately no.

A Cancer charity advices to watch out for symptoms.

Constant Vigilance for cancer recurrence has its own downsides.

After successful cancer treatment, being on look out for symptoms constantly wrecks your quality of life for minimal benefit in most cases.

Many trials of intensive screening shown no benefit for early detection of secondary cancer. ( note- this is different from the ongoing debate about benefits of primary cancer detection with cancer screening programs such as Mammograms, PSA screening, bowel cancer screening).

Cancer patients are quite often aware of own body and pre-existing aches and pains.

The best thing is to act promptly if there are “any new and persistent symptoms” . For vast majority of cancer patients, there is no need to do a frequent check list of possible symptoms, on a daily or weekly interval.

Do NOT be on constant vigilance for all possible cancer symptoms unless you have been specifically advised to do so by your oncology team.

Eternal Vigilance for months and years can wreck your quality of life.

Think Positive. Nothing is lost when you maintain hope.
