One of the leading causes of cancer-related deaths worldwide is lung cancer. Among the various types of lung cancer, squamous cell carcinoma is a common type that usually develops in the central part of the lungs, commonly in the bronchi, and is majorly caused by smoking. Though any type of cancer diagnosis can be overwhelming, early detection can be a crucial factor as it relates to treatment options and overall survival rates. Let's learn about the role early detection plays below.

One of the leading causes of cancer-related deaths worldwide is lung cancer. Among the various types of lung cancer, squamous cell carcinoma is a common type that usually develops in the central part of the lungs, commonly in the bronchi, and is majorly caused by smoking. Though any type of cancer diagnosis can be overwhelming, early detection can be a crucial factor as it relates to treatment options and overall survival rates. Let's learn about the role early detection plays below.
Why is early detection important?
No one likes to think of cancer, not to mention getting tested for it. However, when it comes to this type of cancer, early detection increases the odds of a successful treatment. Let's find out why:- More treatment options: When this cancer is diagnosed early, patients have more options available, such as radiation, targeted therapy, and surgery. When it is detected at an advanced stage, the treatments are often limited to immunotherapy and chemotherapies, which might not be as effective in removing the disease.
- Increased survival rates: Early-stage lung cancer has a better prognosis than advanced-stage diseases. According to research, the five-year survival rate of cancer that has not spread beyond the lungs (localized cancer) is around 63% as against 7% when it has spread to distant organs. Catching squamous cell carcinoma early can mean the difference between effective treatment and a tougher battle.
- Better quality of life: There is no doubt that cancer treatment can be quite tough. However, when this cancer is diagnosed early, the treatment is usually less aggressive, resulting in fewer side effects and a better overall quality of life.

Response: Smoking and tobacco use remains a major health issue. Smokers use cigarette over the course of the day because the levels of nicotine, the addictive agent in cigarettes and other forms of tobacco, dimmish with time in the bloodstream due to the breakdown of nicotine by enzymes in the body. By inhibiting the breakdown of nicotine in smokers, one would expect that the levels of nicotine would remain higher after smoking a single cigarette, and that these individuals may not require lighting up another cigarette so quickly, reducing the number of cigarettes smoked over the course of a day. This could have a profound effect on reducing the overall harm incurred from smoking or from using other forms of tobacco.
In a single previous study, smokers who used a CBD inhaler exhibited a 40% reduction in cigarette use. In addition, while cannabis users are often smokers, previous studies have indicated that they smoke less cigarettes than non-cannabis-using cigarette smokers. In previous studies published in 2021, we found that major cannabinoids present in cannabis like THC and CBD inhibit major metabolizing enzymes in our body, including several that are important in drug metabolism. We hypothesized that CBD and its major active metabolite, 7-hydroxy (OH)-CBD, may also be inhibiting one or more of the enzymes important in the metabolism (or breakdown) of nicotine.

Response: In the NIH sponsored SPIROMICS study we demonstrated that symptomatic, tobacco exposed individuals have frequent exacerbations. Many of these individuals are treated with the same inhaled medications that have shown benefit in COPD, but we don’t have any evidence basis for this practice.

Response: Graphic Warning Labels are to be implemented in the US in July 2022, depending on litigation. This will be about 10 years after they were first proposed. Meanwhile, 120 other countries have implemented them already.
The FDA states that their purpose for the warnings is to provide a constant reminder to smokers about the health consequences of smoking, not to force them to quit.
In our study, 3 months of having cigarettes repackaged into graphic warning packs was associated with smokers thinking more about quitting and not getting as much pleasure out of their cigarettes. However, thinking about quitting is only the first step to conquering a nicotine addiction.
