What are the three phases of cancer development?

The three phases of cancer development include tumor growth, blood vessel development in tumors, and tumor metastasis. Tumor growth refers to the initial phase where abnormal cells start to proliferate uncontrollably, forming a mass or tumor. During this phase, genetic mutations often contribute to the transformation of normal cells into cancerous ones.

Blood vessel development, known as angiogenesis, occurs next as tumors require a nutrient supply to grow. This phase is crucial because it allows the tumor to expand beyond a small size, providing it the resources needed for continued growth and survival.

Finally, during the metastasis phase, cancer cells spread from the original (primary) tumor to other parts of the body, forming new (secondary) tumors. This spread can significantly complicate treatment and impacts the overall prognosis for the affected individual.

Understanding these phases is essential for grasping how cancer progresses and aids in the development of targeted treatments and interventions in the healthcare setting.
