1. Uncontrolled growth: Cancer cells have lost the ability to regulate their growth and division, leading to uncontrolled proliferation.

2. Ability to invade and metastasize: Cancer cells can invade surrounding tissues and spread to other parts of the body through the bloodstream or lymphatic system.

3. Resistance to cell death: Cancer cells can evade programmed cell death (apoptosis), allowing them to survive and continue to grow.

4. Altered metabolism: Cancer cells have a unique metabolism that allows them to thrive in low-oxygen environments and use nutrients more efficiently.

5. Genetic instability: Cancer cells often have mutations in their DNA that can lead to further genetic changes and promote tumor growth.

6. Immune evasion: Cancer cells can evade detection and destruction by the immune system, allowing them to continue to grow unchecked.

7. Angiogenesis: Cancer cells can stimulate the growth of new blood vessels (angiogenesis) to supply nutrients and oxygen to the tumor.

8. Heterogeneity: Cancer cells within a tumor can be genetically and phenotypically diverse, leading to resistance to treatment and disease progression.

Key Properties of Cancer Cells:

1. Uncontrolled Cell Division:
- Cancer cells bypass normal cell cycle checkpoints, leading to uncontrolled cell division.
- This results in the formation of a proliferative mass called a tumor.

2. Evasion of Apoptosis (Programmed Cell Death):
- Normal cells undergo apoptosis when damaged or no longer needed.
- Cancer cells develop mechanisms to evade apoptosis, allowing them to survive and accumulate.

3. Sustained Proliferative Signaling:
- Cancer cells have alterations in signaling pathways that normally regulate cell growth.
- These alterations lead to sustained activation of pro-growth signals, promoting uncontrolled proliferation.

4. Replicative Immortality:
- Normal cells have a finite lifespan and divide a limited number of times.
- Cancer cells acquire the ability to bypass replicative senescence, enabling indefinite proliferation.

5. Angiogenesis (Formation of New Blood Vessels):
- Tumors require a blood supply to sustain their growth.
- Cancer cells secrete factors that stimulate the formation of new blood vessels, providing nutrients and oxygen to the tumor.

6. Tissue Invasion and Metastasis:
- Cancer cells can invade surrounding tissues, breaking through normal tissue boundaries.
- They can also spread to distant sites (metastasis) through the lymphatic system or bloodstream, forming new tumors.

7. Escape from Immune Surveillance:
- The immune system normally targets and destroys abnormal cells.
- Cancer cells develop mechanisms to evade immune detection, allowing them to escape immune surveillance.

8. Metabolic Alterations:
- Cancer cells have a unique metabolic profile, often characterized by:
- Increased glucose uptake and glycolysis (the Warburg effect)
- Reduced oxidative phosphorylation
- Altered lipid and amino acid metabolism

9. Genetic Instability:
- Cancer cells often have a high rate of genetic mutations and chromosomal aberrations.
- These genetic changes drive the development and progression of cancer.

10. Dysregulated Gene Expression:
- Changes in gene expression are common in cancer cells, contributing to altered cell behavior and tumor formation.
- This can involve the activation of oncogenes (promoting cancer) and the silencing of tumor suppressor genes (inhibiting cancer).
