Lung cancer isn't just for smokers: Time to rethink what you know
Since there is increased awareness of lung cancer, some myths concerning lung cancer have prevailed, and many individuals have avoided or delayed lung cancer diagnosis and treatment.
Five such prevailing myths regarding lung cancer and the facts that busted the myths are given below:
Myth 1: Only smokers develop lung cancer
Fact: Smoking is a primary cause of lung cancer but non-smokers are not off the hook either. Fact is that more and more people developing lung cancer never smoked.
Air pollution, secondhand smoke exposure, indoor cooking smoke, genetics, and chemical exposures (such as asbestos and diesel exhaust) are all established risk factors for lung cancer. Even if you don't smoke, you have cause to worry about your lungs.
Myth 2: Lung cancer is for old folks
Fact: Lung cancer risk does accompany growing older, but this doesn't imply that only older people are prone to it. Even individuals as young as their 30s, and sometimes even teens, have been diagnosed with lung cancer, particularly if pollution is a factor or an individual has a family history.

Increasing numbers of young, nonsmoking Indians- especially women -are being diagnosed with lung cancer today than at any other time in history.
This is a time when not any single warning sign concerning lung cancer, or other lung problems, such as coughing, chest pain, and shortness of breath, at any age, should go unnoticed.
Myth 3: If I am not symptomatic then my lungs are healthy.
Fact: Lung cancer has been described as a "silent killer"- that is, there are not necessarily any early obvious symptoms in the progression of disease.
By the time you have symptoms, for instance bloodless or extreme breathlessness, the cancer can already be advanced. Thus, if you are "high risk" like a lifetime smoker or someone with heavy air polluted lifestyle, you should take a visit to your physician and if possible get screened, such as through a low dose CT scan.
Myth 4: Lung cancer is not successfully treatable
Truth: This is so old-fashioned thinking. Due to medical science's advances, we have many patients with lung cancer now living healthier and longer lives.
We now have targeted therapy, immunotherapy, complex surgery, and radiation that were unknown a decade back! Stage 4 lung cancer can be controlled for several years with treatment. While early diagnosis gives the best chance for a good outcome, hope remains.
Myth 5: Only men get lung cancer
Truth: Lung cancer is not gender-specific. In fact, now, we have more and more non-smoking exposed women who have lung cancer, especially in urban areas with so much air pollution and a lot of bad indoor air quality.
And women are more likely to suffer from cooking fume exposure in countries with poor ventilation in kitchens. Such knowledge is important to women in particular. Women may have difficulty recognizing the severity of their symptoms if there is no mental association of their health condition as something serious like lung cancer.
Lung cancer is no longer a smoking disease, or a disease of old people. Lung cancer can affect anyone - at any age and anyone.
The silver lining is that with early diagnosis and current treatment, more lives than ever before are being saved.
If you have a persistent cough, chest pain, shortness of breath or mysterious tiredness - don't brush it off. Have it investigated by your doctor, particularly if you reside in a region with high levels of pollution or have a documented exposure to smoke or chemicals.
No more myths are needed to do the damage the disease itself does.

Tamil Nadu's Water Bell Scheme: A Step Towards Better Hydration and Sanitation in Schools
Water bell in schools is a start. Toilet audit is way forward: With poor bathroom-student ratios, 70% of schools lacking inclusive facilities, and students often being shamed for needing a restroom break, Tamil Nadu's latest school initiative on hydration needs to go hand in hand with improvements in sanitation. Pic credit R Baskar R S Raveendhren On June 28, the Tamil Nadu govt announced its 'Water Bell Scheme' to be implemented in all schools across the state to encourage students to drink water and to bring home the importance of hydration. Initially introduced in Kerala, Karnataka, Telangana and Odisha, the scheme has managed to hit two birds with one stone by bringing into focus not just the importance of water breaks but also the issue of 'continence culture' among school students. You Can Also Check: Chennai AQI | Weather in Chennai | Bank Holidays in Chennai | Public Holidays in Chennai World Toilet Day, celebrated every year on Nov 19, reiterates the crucial role played by sanitation in our lives and the compelling need for cleaner and safer toilets. Management of toilets in schools represents a critical aspect of public health. Without access to a safe and clean school toilet, the ability of students to learn and realise their full potential will remain severely compromised. In this context, school toilets and pedagogy are inextricably linked. Many schools do not permit their students a bathroom break whenever they request one, or worse, in some cases, they are made to feel uncomfortable for seeking permission frequently to use the bathroom, leading to social anxiety and embarrassment. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Gentle, Needle-Free Way to Monitor Blood Sugar—Now Being Tried by Seniors Zakdavi Undo Besides this, lack of earmarked time and poor toilet sanitation dissuade a majority of students from using restrooms. The urinary bladder needs to be emptied every three hours. Students who want to avoid poorly-maintained toilets often resort to limiting water intake. Urologists express renewed concerns that more and more children, especially girls aged between five and 15 years, are seeking medical help for serious health issues such as constipation, recurrent abdominal pain and urinary tract infection. According to them, these conditions can be directly traced to poor toilet habits, which arise from a disproportionate number of toilets in schools and public spaces, insufficient time or attention given to toilet use, or complete avoidance due to poor sanitation. In many developing countries, the lack of separate toilets for boys and girls is a daunting issue, often leading to girls dropping out of school at puberty. For a country with 248 million students and counting, it is shocking that there is no comprehensive toilet policy for schools, unlike in countries in the West. The World Health Organization (WHO) prescribes at least one toilet for every 25 girls, manned by one female staff, and one toilet for every 50 boys, manned by one male staff. While the 'Swachh Bharat, Swachh Vidyalaya' Scheme prescribes one toilet and three urinals for every 40 students, the Tamil Nadu Private Schools (Regulation) Rules, 2023, stipulate a ratio of one toilet for every 50 children and one urinal for every 20 children, both of which are starkly behind global norms. The Right of Children to Free and Compulsory Education Act, 2018, surprisingly failed to lay down any such ratio. As of today, there is no legal framework governing this subject except for inconsistent norms that often clash with each other. A report from the Comptroller and Auditor General (CAG) presented before Parliament a few years ago pointed out that 40% of govt co-educational schools in India either had no toilets or unused ones. About 72% of them have zero maintenance, with more than half lacking running water. Tamil Nadu may be doing much better than other states by providing separate toilets for girls in 99.7% of govt schools. However, the latest report from the Union Ministry of Education under the Unified District Information System for Education Plus states that there is still a long way to go. About 70% of the 58,801 govt, govt-aided and private-unaided schools lack toilets suitable for students with special needs; 26% of these schools are not provided with ramps and 59% lack handrails, leaving them more disadvantaged in terms of using the restroom facilities. In 2019, the Tamil Nadu health department made it mandatory for educational institutions to provide soap and running water, without which sanitation certificates were withheld. Students and parents were encouraged to raise complaints about poor sanitation in school toilets by directly calling the '104' helpline and/or to raise concerns with their district health officials. There is no doubt that students need encouragement to use toilets frequently without feeling shy about relieving themselves. The water bell scheme must be complemented with a toilet bell. Neat and tidy toilets where students feel safe, private and comfortable will play a significant role in creating positive consequences on their physical and mental health. A safe toilet is a matter of right and not a privilege. The UN Committee on Economic, Social and Cultural Rights (ESCR) affirms sanitation as fundamental for human survival. It is declared as a fundamental right under Article 21 of the Constitution of India and an integral facet of the right to live with dignity by the Supreme Court. The UN has observed that sanitation has to progress at five times the speed to attain Goal 6 (clean water and sanitation) of the Sustainable Development Goals by 2030. A toilet is a good indicator of the governance of a society. A toilet audit by committees comprising students, parents, health officials and regulatory bodies could pave the way for greater awareness of sanitation. Another way to ensure janitors are doing their job well in school toilets is to use technology to launch an application that provides real-time updates on toilet maintenance in all educational institutions, also making authorities accountable for their lax behaviour.
