Problem being Solved:

Lung cancer is a serious and common disease that affects millions of people around the world. It is caused by genetic damage to the cells in the lungs, often due to smoking or exposure to harmful substances. Lung cancer can cause symptoms such as difficulty breathing, coughing up blood, chest pain, hoarseness, headache and weight loss. Lung cancer can be diagnosed by various tests such as X-rays, CT scans, MRI scans, PET scans, sputum cytology and biopsy. Lung cancer can be treated by surgery, chemotherapy and radiation therapy, depending on the type and stage of the cancer.

The inspiration for doing this project on lung cancer is to raise awareness about this disease and its prevention. Lung cancer is the leading cause of cancer deaths worldwide, but many people are unaware of its risk factors and symptoms.

Additionally, the RespiScan 2.0 project could potentially be used for public health education and awareness campaigns. By highlighting the risk factors and symptoms of lung cancer, the model could help raise awareness and encourage individuals to take steps to reduce their risk of developing the disease. This could include initiatives to promote smoking cessation, improve air quality in workplaces, and encourage early detection and treatment through regular screenings.

However, it is important to note that any diagnostic tool, including the RespiScan 2.0 model, would need to be thoroughly validated and tested before being used in a clinical setting. This would involve testing the model on a large and diverse population of patients to ensure that it is accurate and reliable across different demographics and patient groups.

Overall, the RespiScan 2.0 project has the potential to improve the early detection and treatment of lung cancer, which could have significant benefits for patient health and survival rates. However, further research and testing would be needed to ensure that the model is accurate and reliable for use in a clinical setting.

How is the Work is experienced or used in production:

RespiScan 2.0 can be experienced and used in production as a user-friendly tool for individuals who want to assess their risk of developing lung cancer from the comfort of their own homes. Users can input their basic information and symptoms into the RespiScan 2.0 model, and receive a prediction of their likelihood of having lung cancer.

The model could be integrated into a web-based platform or mobile application, which could be easily accessed by users. The platform could also provide educational resources on lung cancer prevention and early detection, which could help users reduce their risk of developing the disease.

Overall, RespiScan 2.0 has the potential to be a valuable tool for individuals who are concerned about their risk of developing lung cancer, as it can provide a quick and convenient way to assess their risk and take appropriate action to prevent or detect the disease.
