1.which section of the cell does cancer have an effect on?

~the genes controlling the cell division?

2.what charteristic of cancer cells lets cancer to extend to other spots of the body?

~Malignant tumours(metastasis)?

3.y r cancers that metastasize more precarious than cancers which don't?

~please help

Thanks a lot 4 all ur help:-)

1. Cancer primarily affects the genes controlling cell division. More specifically, it disrupts the normal regulation of cell growth and division, leading to uncontrolled cell proliferation. This can occur due to mutations or alterations in the DNA of cells, particularly in genes called oncogenes and tumor suppressor genes. These alterations can result in the loss of control over the cell cycle and the ability of cells to stop dividing when necessary. As a result, the affected cells continue to divide and form a tumor.

To learn more about the specific genes affected by cancer and their role in cell division, you can explore cancer biology textbooks, scientific articles, or reliable online resources. By studying the molecular mechanisms and genetic factors involved in cancer development, you can gain a better understanding of how cancer impacts the cell's ability to divide normally.

2. One characteristic of cancer cells that enables them to spread to other parts of the body is their ability to form malignant tumors and undergo metastasis. Malignant tumors are cancerous growths that have the potential to invade nearby tissues and spread to other distant sites through the bloodstream or lymphatic system.

In contrast to benign tumors, which tend to remain localized and are less invasive, malignant tumors have the ability to break away from their original site and enter the bloodstream or lymphatic system. Once in the circulation, cancer cells can travel to different areas of the body and establish new tumors, leading to the spread of the disease.

Understanding the process of metastasis and the factors that contribute to the invasive behavior of cancer cells involves studying the mechanisms of tumor cell migration, invasion, and interaction with the surrounding microenvironment. Scientific research articles, cancer biology textbooks, or educational websites can provide more detailed information on this topic.

3. Cancers that metastasize (spread to other parts of the body) are generally more dangerous and difficult to treat compared to cancers that don't metastasize. There are a few reasons for this:

a. Increased tumor burden: When cancer spreads, it often leads to the growth of multiple tumors in different areas of the body. Having more tumor sites can put a greater strain on the body and make it harder to control or eliminate the cancer entirely.

b. Difficulties in targeting metastatic tumors: Some cancer treatments, such as surgery or radiation therapy, are more challenging to apply to multiple tumor sites spread throughout the body. Metastatic tumors may be located in vital organs or inaccessible areas, making them harder to remove or effectively target with therapy.

c. Resistance to treatments: Metastatic cancer cells can acquire resistance to treatments, making them less susceptible to traditional cancer therapies. This resistance can result from genetic changes occurring in the cancer cells over time or from the presence of cancer stem cells, which have a higher capacity for self-renewal and resistance to therapy.

d. Overall impact on organ function: Metastatic tumors can disrupt organ function and cause complications specific to their location, leading to additional health issues and decreasing overall quality of life.

To delve deeper into the reasons why metastatic cancers are more precarious, you can refer to medical literature, oncology textbooks, or consult with oncology experts who can provide detailed insights based on the specific type and stage of cancer being discussed.
