How does cancer affect the tissues in levels of organization an organism with pictures?

Cancer affects the tissues in an organism on multiple levels of organization, from the cellular level to the organ and system level. Here's how cancer can affect tissues at different levels, along with images for each level:

1. Cellular Level:

- Cancerous cells undergo uncontrolled growth and division, leading to the formation of a tumor.

- They have abnormal structures and may lose their specialized functions.

- The tumor cells can invade and destroy surrounding healthy tissue.

2. Tissue Level:

- Cancerous tumors can disrupt the normal organization and structure of tissues.

- The tumor's growth can compress and damage surrounding tissues, leading to functional impairments.

- It can result in the loss of tissue-specific functions and tissue dysfunction.

3. Organ Level:

- Tumors growing within organs can affect their structure and function.

- As tumors enlarge, they can obstruct essential passages or blood vessels, disrupting normal organ function.

- The tumor can also affect the organ's ability to carry out its specific roles.

4. System Level:

- Cancer can spread from its original location (primary tumor) to other parts of the body through metastasis.

- Metastatic tumors can develop in different organs and tissues, leading to multiple organ system dysfunctions.

- The systemic effects of cancer can cause a range of symptoms and complications.

5. Organismal Level:

- Advanced cancer can have a significant impact on the overall health and well-being of an organism.

- It can cause weight loss, fatigue, pain, and other systemic symptoms.

- In severe cases, cancer can lead to organ failure and death.
