Lung cancer is the hysterical growth of unbalanced cells in one or the two lungs. These unusual cells don’t complete the elements of typical lung cells and don’t form into solid lung tissue.
A lot of these questions arise as to what is exactly Lung cancer. So explain it in a very easy way that it is a condition that causes cells to divide in the lungs uncontrollably. This can result in the growth of tumors that reduce a person’s ability to breathe. Similar to other types of cancer if is not very easy to depict that it is a form of Cancer. Identifying lung cancer in its initial stages is difficult as the symptoms may be similar to those of a respiratory infection, or there may be no symptoms at all.
How Lung Cancer Grows in a Body
A cancer begins with a defect or transformation in a cell’s DNA. DNA changes can be caused by the normal aging process or through ecological factors.
Reasons for Lung cancer may be majorly cigarette smoking, breathing in asbestos fibers (Silicon Minerals) and to exposure to radon gas (radioactive, colorless, odorless, tasteless noble gas)
It has been globally proved that this Lung Cancer progresses due to incremental changes in cells and form Lung cancer. Before ending up completely cancerous, cells can be precancerous, in that they have a few mutations yet at the same time work ordinarily as lung cells. At the point when a cell with a hereditary mutation separates. With each new mutation, the lung tissue cell turns out to be more changed and may not be as powerful in completing its capacity as a lung cell. At a later phase of sickness, a few cells may travel far from the first tumor and begin developing in different parts of the body. When cancerous cell spreads to other part of body then it is called metastasis
Approximately survival rate for this cancer is around 10%. Nearly 1 lakh Lung cancer patients are there in India who have been detected with Lung Cancer
Risk factors and Causes for Lung Cancer
A number of factors known to promote/increases risk of lung cancer.
Symptoms of Lung Cancer
Similar to other Cancers like Cervical Cancer there are hardly any sure symptoms of Lung cancer. It is normally depicted and noticed in advance stages.
A person should consult a doctor if they see any single or multiple symptoms as below
Less Common Symptoms of Lung Cancer
These symptoms are usually associated with more advanced lung cancer
• Difficulty in swallowing
• Hoarseness in voice
• Swelling in the neck caused by enlarged lymph nodes.
• Repeated attacks of pneumonia
• Rise in platelet count (thrombocytosis)
• Pain under the ribs on the right side
• Changes in the shape of fingers and nails, called finger clubbing
How Lung Cancer get diagnosed?
Initial stage diagnosis can be the cure for Lung Cancer however the symptoms of lung cancer are not very evident. Hence patients get to know about it quiet late hence treatment is difficult to cure. The early symptoms of lung cancer are constant cough, chest pain and shortness of breath are similar to other lung problems such as an infection or long-term effects of smoking and are not taken notice of. This often delays the diagnosis.
How Can you Identify/ Screen for Lung Cancer
Tests to detect a disease in patients who do not have symptoms of the disease which is called Process of screening. For lung cancer, three tests have been studied for use as screening tests:
Few criteria for screening
Though screening can detect lung cancer better than X-ray chest, one must remember that not all lung cancers are found by LDCT screening and not all lesions detected by LDCT are cancer.
Diagnosis of Lung Cancer
If either of the symptoms is observed, you should consult the doctor. There will be further tests advised and you should refer to an appropriate Test Center for Chest X-ray, CT Scan, CT guided Biopsy, MRI and PET Scan
If there is difficulty in breathing, removal of fluid can help the patient breathe better.
How Lung Cancer is Treated?
The treatment of lung cancer depends on the type and size of the tumor. Several surgeries, chemotherapy, radiotherapy and targeted therapy may be used alone or in combination depending on the above mentioned factors.
Few medicines which can support the therapies are Paclitaxel, Carboplatin, Cisplatin, Docetaxel, Etoposide, Gemcitabine, Pemetrexed
Few key inhibitors of Epidermal growth factor receptor (EGFR) medicines are Erlotinib and Gefitinib. Also for Monoclonal antibody against EGFR Cetuximab is referred
Key inhibitors of vascular endothelial growth factor (VEGF) is Bevacizumab and for inhibitor of EML4-ALK is Crizotinib
What are the Prevention steps from Lung Cancer
Other Key medicines used in Lung Cancer are Lorlatinib, Alectinib, Brigatinib, Durvalumab, Keytruda, Opdivo, Osimertinib and Atezuluma.
