Reaching out to the community

In parallel with his efforts at surgical intervention and innovation to save those who attempt to take their own lives by drinking acid, Prof. Chandramohan has also worked for more than two decades to create awareness about good gastrointestinal health, cancer, suicide prevention, drug abuse and other societal concerns.

What began as a crusading spirit at the turn of the century has today become an established movement, aided and pursued by the ESOINDIA ( non-governmental organisation that Prof. Chandramohan established.

In the initial phase, Prof. Chandramohan took his dedicated team of doctors and professionals to conduct health camps in remote centres, such as Coonoor in the Nilgiris (2001), Nagapattinam in the aftermath of the Asian tsunami (2004). He later cast his net wide, involving students and youth, for a variety of awareness programmes using the medium of essay writing, speech contests and art displays. Prize winners among the essayists and contributors were chosen for making original, distinct contributions on how cancer of the GI tract could be prevented, identified early, treated and managed.

Several Camps are held every year to mark important days observed by WHO and competitions held on that theme. The prize-winning entrants have been chosen from around the State. Hundreds of entries were received by Prof. Chandramohan in response to his call, in areas such as gastric cancer prevention, drug abuse awareness, and mental health. The scores of winners then got an opportunity, at the special awareness programmes to interact with a wide audience, as well as meet survivors of cancer and acid-drinking episodes.

The most recent of these events was held in Chennai during Independence Day 2019 on August 15, while a mega outreach camp to help tribal populations was conducted, also during the year, at Kotagiri in the Nilgiris district of Tamil Nadu.

As a persuasive speaker in Tamil, Dr. Chandramohan coined the clarion call “Vizhithezhu” (Arise, Awaken) to galvanise civil society in the State to participate in cancer awareness programmes. Programmes under this banner were held in Chennai and Kodaikanal, where prominent members of the arts such as musicians and actors participated along with youth and students who took part in the contests. These programmes are detailed on the ESOINDIA website, and presented in multimedia form on the organisation’s YouTube channel.

He has formed Gastric Cancer Help Group and Esophageal Patient’s Support Organisation with Survivor Volunteers and Supporters and they play a pivotal role in conducting the awareness programme.

For the energetic, community-focussed Prof. Chandramohan, these two decades of efforts only mark a beginning, and higher levels of engagement with patients and community is a constant pursuit.  All these he has done as in Individual with Social commitment with the help of Survivor Volunteers and ESOINDIA which he founded.
