The three main causes of cancer are smoking, diet and exercise. The prevention of cancer is mainly in the hands of the people based on the lifestyle they choose to lead.
Answer:
Age and genetics are the largest causes of cancer. Lifestyle choices are a lower risk factor. Some people are predisposed to cancer. Age ( and the number of cell replications) reduces the length of the telemeres in the DNA molecules which cause replication errors (cancers) in the cells.

When cells stop responding to normal controls over growth and division they?
may undergo uncontrolled growth, leading to the development of a tumor or cancer. This loss of normal growth control can be driven by various factors, such as mutations in key regulatory genes or exposure to certain carcinogens.
How does productivity increase in aquatic ecosystems and what factors contribute to this growth?
Productivity in aquatic ecosystems increases through the process of photosynthesis, where plants and algae convert sunlight into energy. Factors that contribute to this growth include nutrient availability, sunlight, temperature, and water quality.
What are the key differences between normal tissue and cancerous tissue?
Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
Why the cells depicted in line A are most likely cancerous?
The cells in line A are likely cancerous because they appear crowded, irregularly shaped, have enlarged nuclei, and are not organized in a uniform manner as normal cells. These characteristics suggest uncontrolled growth and division typical of cancerous cells.
Which hormones must increase for endometrial growth to occur?
For endometrial growth to occur, the hormones estrogen and progesterone must increase.
State the name given to agents that increase the chances of cancerous growth?
Carcinogens or mutagens
Will normal or cancerous cells have a higher growth rate?
the cancerous cells
When is surgery necessary for thyroid?
(1) When you have a cancerous growth (2) when you have a non-cancerous growth that pushs into the neck, causing other things in the neck to be squeezed (3) and this is the most likely case, when they can't tell from the biopsy if the growth is cancerous or not.
What are the factors affecting economic growth in the UK?
Economic growth is measured by an increase in the real Gross National Product of a country or its GDP. There are two types of economic growth, long run and short run economic growth. Short run economic growth is caused by an increase in the aggregate demand of an economy, otherwise referred to as AD. AD is made up of four factors, consumption, investment, government spending and the net worth of imports and exports. An increase in any of these factors can lead to an increase in real GDP. Long run economic growth is caused by an increase in the quality or quantity of the factors of production of the economy. These FOP's are land, labour, capital and enterprise. An increase in any of these factors will cause an increase in the potential output of an economy meaning it has the potential to produce more.
What will A cancerous growth on the skin will likely exhibit?
asymmetry
Would a growth factor increase or decrease cyclin levels?
A growth factor would increase cyclin levels. Growth factors signal a cell to enter the cell cycle, which involves an increase in cyclin levels to regulate cell division.
Will the river bed roughness increase or decrease?
The roughness of a river bed can increase due to factors such as sedimentation, debris, and vegetation growth. If these factors are left unchecked, they can lead to an increase in roughness over time.
What of these factors contributed to the growth of post classical empires?
An increase in regional interaction. Apex
How the presence of a cancerous tumor affect the biological processes?
Cancerous tumours are formed from cells which have had mutations in very specific genes which have allowed them to survive independantly of cells around them in the body. Some of these key genes code for growth factors and other proteins which affect normal body cells. Often the tumour cell mutations cause upregulation of these growth factors causing neighbouring healthy cells to be affected in unusual ways.
Do Such mutations would increase or decrease the activity of genes that produce growth factors?
Mutations can either increase or decrease the activity of genes that produce growth factors. It depends on the specific nature of the mutation and how it affects the function of the gene. Mutations can disrupt the normal regulation of gene expression, leading to either increased or decreased production of growth factors.
What are brain and spinal cord tumors?
Masses that grow within the brain or spine. The growths usually cause many complications with growth and other such factors. The masses could be cancerous or not.
Growth occurs due to what?
Growth occurs due to an increase in the number and size of cells in an organism. This process is regulated by various growth factors, hormones, and genetic factors that control cell division and differentiation. Environmental factors such as nutrition, exercise, and stress can also influence growth.
