  After the pandemic of SARS-CoV-2, it has influenced the health care practices
around the world. Initial investigations indicate that patients with
comorbidities are more fragile to this SARS-CoV-2 infection. They suggested
postponing the routine treatment of cancer patients. However, few meta-analyses
suggested evidences are not sufficient to hold the claim of the frailty of
cancer patients to COVID-19, and they are not in favour of shelving the
scheduled procedures. There are recent studies in which medical professionals,
according to their competence, are referring to change the routine practices on
how to manage the applicable therapeutic resources judiciously to combat this
vital infection. This is a different study that reveals the cancer patients'
viewpoint about how health care practices have been changed in their opinion
during this pandemic year? Are they satisfied with their treatment or not? To
serve the purpose, we gathered more than 60000 relevant tweets from Twitter to
analyse the sentiment of cancer patients around the world. Our findings
demonstrate that there is a surge in argument about cancer and its treatment
after the outbreak of COVID-19. Most of the tweets are reasonable (52.6%)
compared to the negative ones (24.3). We developed polarity and subjectivity
distribution to better recognise the positivity/negativity in the sentiment.
Results reveal that the polarity range of positive tweets is within the range
of 0 to 0.5. Which means the tendency in the tweets is not so much positive but
surely not negative. It is a piece of modest statistical evidence in support of
how natural language processing (NLP) can be accepted to better understand the
patient's behaviour in real-time, and it may facilitate the medical
professional to make better decision to organise the routine management of
cancer patients.
