Characteristics of Cancer Cells — Prelims Strategy

Prelims Strategy

To excel in NEET questions on 'Characteristics of Cancer Cells,' adopt a multi-pronged strategy. Firstly, master the 'Hallmarks of Cancer' framework. Understand each hallmark (e.g., sustained proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis) and the underlying biological mechanisms.

Create flashcards for each characteristic, noting its definition and how it differs from normal cell behavior. Secondly, focus on key terminology. Terms like anaplasia, pleomorphism, contact inhibition, anchorage dependence, telomerase, VEGF, and MMPs are frequently tested.

Ensure you can define them precisely and understand their significance in cancer. Thirdly, practice comparative analysis. Many questions will ask you to compare normal cells with cancer cells, or benign tumors with malignant ones.

Create comparison tables during revision. Fourthly, understand the 'why' behind each characteristic. For example, why do cancer cells evade apoptosis? (To survive despite damage). Why do they induce angiogenesis?

(To get nutrients for rapid growth). This conceptual understanding helps in answering application-based questions. Finally, be wary of trap options. Distractors often include terms related to general cell biology (e.

g., DNA repair, transcription) or other forms of abnormal growth (e.g., hypertrophy, hyperplasia, metaplasia) that are not the specific characteristic being asked. Always read the question carefully to identify the precise characteristic being tested.
