The main types of lung cancer are non-small cell lung carcinoma and small cell lung carcinoma, the two being distinguished histologically as well as by how they are treated; non-small cell lung carcinoma is primarily treated with surgery if feasible, while small cell lung carcinoma is more frequently treated with chemotherapy and radiation.
Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor. Without treatment, tumors spread throughout the lung, damaging lung function. Eventually lung tumors metastasize, spreading to other parts of the body. Early lung cancer often has no symptoms and can only be detected by medical imaging.
Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.
Chemotherapy for NSCLC usually includes combination of two drugs (chemotherapy doublet), with one of the agents is cisplatin or carboplatin. In 2002, Schiller at al. published in the New England Journal of Medicine, a study that compared four chemotherapy regimens for advanced NSCLC, cisplatin and paclitaxel, cisplatin and gemcitabine, cisplatin and docetaxel, and carboplatin and paclitaxel.

The incidence of bronchiolo-alveolar carcinoma has been reported to vary from 4–24% of all lung cancer patients. [23] An analysis of Surveillance epidemiology and End results registry ( SEER) by Read et al. revealed that although the incidence of BAC has increased over the past two decade it still constitutes less than 4% of NSCLC in every ...
According to a broad medical consensus, limited-stage small cell lung carcinoma is generally considered to be encompassed within a radiation portal. [4] [5] Variability in categorising small-cell lung cancer as limited or extensive occurs with reference to the extent of pleural effusion and nodal stations involvement.
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
When most tumors metastasize to the lung, they form distinct nodules, but about 7% spread through the lymph vessels of the lung. [2] They may impair breathing in several ways; the lung becomes stiffer; blood vessels traveling alongside the distended lymph vessels become compressed. [3]
