Naval Veterans Found to Have High Lung Cancer Cases Connected to Asbestos

The report discusses how asbestos exposure led to increased occurrences of asbestos-related lung cancers among navy personnel. This insight stems from a joint study conducted by the University of Adelaide and Oxford University, analyzing data from British and Australian troops who served in the 1950s and 1960s, a period when asbestos-containing materials were prevalent on naval vessels.

The study initially focused on radiation exposure from British nuclear testing but discovered a higher incidence of mesothelioma, strongly linked to asbestos, in naval personnel across all cohorts. 

Dr. Richie Gun from the University of Adelaide and Dr. Gerry Kendall from Oxford University further delved into this data, examining the occurrence of lung cancers associated with asbestos exposure.

Their findings revealed a higher overall rate of lung cancer among naval personnel compared to other armed services, and although smoking remains the primary cause of lung cancer, the excess observed in the navy couldn't be solely attributed to a higher smoking rate.

The absence of actual airborne asbestos level measurements made estimations challenging, yet the researchers concluded that the elevated lung cancer rate among sailors likely resulted from onboard asbestos exposure. They reinforced this conclusion by noting deaths among sailors due to asbestosis, a non-cancerous but potentially fatal condition associated with asbestos exposure.

Their estimates indicated that approximately 27% of lung cancers in Australian seamen and 12% in British seamen were linked to onboard asbestos exposure.

Despite strict regulations in Australia concerning asbestos-containing materials, there were still reported cases of asbestosis-related deaths, emphasizing the ongoing risk to workers and some households.

Dr. Gun highlighted the importance of considering lung cancer alongside mesothelioma and asbestosis when evaluating the effects of asbestos exposure. While acknowledging smoking as the primary cause of lung cancers, he emphasized the contribution of agents like asbestos to cancer incidence in exposed populations.

Additionally, the study revealed an enhanced risk of lung cancer due to the combined impact of smoking and asbestos exposure.

The report's findings underscore the significance of stringent measures to safeguard workers from exposure not only to asbestos but also to other harmful airborne particles, such as those from engineered stone found in many kitchens. Dr. Gun stressed the necessity for strict control measures to protect workers from various hazardous dusts beyond asbestos.

Pleurocentesis (Thoracentesis) Procedure, Risks & Complications

Image
Pleurocentesis :  Before we let you know about Pleurocentesis risks, procedures and complication, you first need to know what exactly is Pleurocentesis. Pleurocentesis is also called Thoracentesis which is a surgical procedure used to remove excess fluid from the pleural spaces of the lungs. By undergoing this procedure, doctors are able to treat or diagnose various types of pleural effusions. As Pleurocentesis is minimal invasive, doctors sometimes use it as palliative treatment for certain type of pleural mesothelioma patients.   What Is a Pleurocentesis (Thoracentesis)? As we mentioned above, Pleurocentesis is basically a surgical procedure which can be minimal invasive and used to remove excess fluid from pleural cavity of lungs using a hollow needle. It all happens due to prolonged asbestosexposure that results in diseases like mesothelioma.  And when it happens, excess fluid in the lungs starts building up. In such a scenario, it can lead to various discomforts like

Top Reasons Why Military Personnel Become Easy Target of Mesothelioma

Mesothelioma is basically a type of lung cancer that occurs mainly due to the asbestos exposure over a period of several years or decades. It develops quite slowly and steadily. The reason why it is a severe type of cancer is because of the fact that it takes the linings and tissues of the coverings of internal organs called mesothelium. And so, it mainly attacks on the linings of lungs and the rest of the abdomen. Due to the severity of mesothelioma, almost 3,000 people are diagnosed with this form of lung cancer every year. There are treatments available that can only alleviate the symptoms to some extent. But there is no complete cure available to recover a patient. In most cases, the victims of mesothelioma are known to have a life expectancy between 19-31 months. With the onset of new and advanced treatment, the survival rate can be increased. Even then, the survival rate in such patients has been found to be quite low due to the severity of the disease. Patients with mesothe

Face Swelling A Sign of Lung Cancer : Do you know that lung cancer happens to be the second most common type of cancer globally? Well, the worst thing is that it affects men and women both. It means no one is safe from this dreaded disorder. It's also the leading cause of most causalities happening across the globe. As per records, more than 2 lakh people are diagnosed with lung cancer and the number id constantly increasing. In some countries, lung cancer rate is increasing at a faster rate as compared to other countries. As per experts, early detection of lung cancer can help in the survival rate. And so, people need to be cautious regarding changes in their bodies. At the same time, it is crucial to know the causes and symptoms of lung cancer so that you can stay protected from the disease. In a recent study by scientists, face swelling is being connected with the occurrence of lung cancer. In other words, most experts believe that if you notice a swelling on your face, it m
