2. Small-cell carcinoma - Wikipedia

   en.wikipedia.org/wiki/Small-cell_carcinoma

   Small-cell carcinoma is a type of highly malignant cancer that most commonly arises within the lung, [1] although it can occasionally arise in other body sites, such as the cervix, [2] prostate, [3] and gastrointestinal tract. Compared to non-small cell carcinoma, small cell carcinoma is more aggressive, with a shorter doubling time, higher ...

3. Combined small-cell lung carcinoma - Wikipedia

   en.wikipedia.org/wiki/Combined_small-cell_lung...

   Oncology. Combined small cell lung carcinoma (or c-SCLC) is a form of multiphasic lung cancer that is diagnosed by a pathologist when a malignant tumor, arising from transformed cells originating in lung tissue, contains a component of small cell lung carcinoma (SCLC) mixed with one or more components of any histological variant of non-small ...

4. Limited-stage small cell lung carcinoma - Wikipedia

   en.wikipedia.org/wiki/Limited-stage_small_cell...

   Limited-stage small cell lung carcinoma (LS-SCLC) is a type of small cell lung cancer (SCLC) that is confined to an area which is small enough to be encompassed within a radiation portal. [1][2][3][4] This generally includes cancer to one side of the lung and those might have reached the lymph nodes on the same side of the lung. 33% patients ...

5. Lung cancer - Wikipedia

   en.wikipedia.org/wiki/Lung_cancer

   1.8 million (2020) [3] Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.

6. Cancer of unknown primary origin - Wikipedia

   en.wikipedia.org/wiki/Cancer_of_unknown_primary...

   Because stem cells have a natural ability to migrate and also play a key role in cancer development, it has been proposed that a cancer of unknown primary site may form when deregulated, premalignant or cancerous stem cells migrate away from their natural tissue and give rise to a cancer in the new site before or without generating a tumor in ...

7. Cancer stem cell - Wikipedia

   en.wikipedia.org/wiki/Cancer_stem_cell

   The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex [6] (Fig. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations [7] They have two defining features: their long-term ability to self-renew and ...
