Cancer cells can float in a person’s blood. But finding them, in the past, used to be like “looking for a needle in a haystack”.
But new smart technology promises to detect these cancer cells easily and much early before a person develops symptoms. Detection of cancer cells at an early stage may be helpful for some patients.
A Californian company called Grail has developed a blood test which seems to have a high degree of accuracy for detection of multiple cancers.
Times newspaper reports that “The NHS will begin a pilot scheme of the test with 140,000 people this year. If that is successful it will be used for millions of patients by 2025”
A word of caution though.
Just because something could be diagnosed early does not always mean that it is a good thing.
The most important thing is whether the early diagnosis can lead to better cure rates and a better quality of life.
If a test detects a cancer early but has no meaningful effect on quantity or quality of life, then it is not a good thing.
For example. Up to 80% of men have prostate cancer which can now be detected by a simple blood test called PSA. There is a good reason why we are NOT using the simple PSA test in every 80 year old.
Most 80 year old men die WITH prostate cancer rather than DUE to prostate cancer.
So why diagnose a cancer that is not causing symptoms if it is not going to make person live longer !

A recent study published in the esteemed Lancet Oncology Journal shows that the vaccine is well tolerated in patients having immunotherapy.
Unlike cancer chemotherapy, immunotherapy works differently. It works by releasing the in-built brakes holding down the immune system thereby boosting the body’s immune system against cancer.
There has been some theoretical concerns whether this might lead to COVID vaccine causing more side effects.
Reassuringly, the Vaccine side effects were NO different from those seen in people not having immunotherapy. The Vaccine also did NOT increase the immunotherapy side effects.
So the study is good news for tens of thousands of patients on immunotherapy and any cancer patient who has hesitated before, should seriously consider having the vaccine now
COVID infection could be very nasty in cancer patients and all evidence points to the benefits of vaccine far outweighing any risks from the Vaccine.

It might seem foolish to ask the question “Anything good from this COVID-19 pandemic?” when so many people across the world has been so badly affected by the coronavirus pandemic.
There is some truth in the proverb that “every dark cloud has a silver lining” and no matter how bad the current pandemic is now, human spirit and endeavour would get something positive out of it.
One possible good thing that has come out of the pandemic is the “mRNA technology”.
The successful use of RNA technology for Coronavirus Vaccines would hopefully enable the versatile RNA technology to be further developed and successfully used a cancer treatment in near future.
Further clinical trials in cancer patients would be done to provide proof of their potential.

The guidelines indicate that anticipated benefits of vaccine are greater than unknown risks from the Coronavirus vaccines.
The Vaccine trials deliberately included lot of healthy people. Very few people with cancer, particularly cancer patients on active treatment, were included in the COVID-19 trials. So there is not much direct evidence regarding efficacy and safety of Vaccines in cancer patients. But indirect evidence significantly favours Coronavirus vaccination in cancer patients.

The Staff at National Health Service in UK are doing an admirable job during the pandemic. In the particular, the frontline staff (“patient-facing”) are showing great courage in face of great difficulties and are primarily driven by altruism.
But the pressures of pandemic means many routine scans and hospital clinic appointments have been cancelled particularly during the first wave. There is a great worry about delayed diagnosis of cancer and delayed treatment of cancer.
A paper in BMJ reports that cancer patients survival can be significantly compromised.
But, as with everything else in life, things are not always what they look like at first impression. Even things that are logical and common sense at first glance do not turn out to be simple and clear.
Firstly, delays and cancellations of scans paradoxically could have psychologically benefited some cancer patients . This might seem counterintuitive or even an outrageous statement.
But there are some cancers which are being over diagnosed. A Cancer diagnosis does not always mean a death sentence. Some cancers do not cause problems for a long time or never in the life time of a person. These cancers do not need to be diagnosed promptly. Not being diagnosed with these cancers prevents the psychological burden of a cancer diagnosis. This “over diagnosis” would be expectedly less during pandemic.
Secondly, treatment delays could be caused by a cancer that is advanced and the need for time consuming additional investigations and procedures. Sometimes delays are caused by patients needing to see many medical specialists for the treatment. So it’s the aggressive cancer and the complex patient care that would cause the delay and is responsible for poor outcome rather than the delay by itself.
Elderly cancer patients on the whole did very badly but surprisingly cancer patients under age of 50 did far worse than their peers without cancer.
