Describe how effective communication of feelings could help me to prevent adverse effects of emotional stress

Answers

Explanation:

doesn’t always help. There are some things that can make you more emotional the more you bring it up. But there are times, especially when a problem is new to us, that our thoughts get so tangled up, our emotions can become magnified.

When you hear your own voice out loud, you remove a lot of the clutter that gets added to your thoughts when they’re fuelled with emotion. You have a chance to simplify matters, by dropping out a large proportion of unnecessary worry. You can’t always distinguish the unnecessary worry when you’re emotions are locked in your head at the mercy of your imagination. But you hear them almost instantly when said out loud in the presence of someone you trust.

Having someone hear you, helps you realize how normal these things are too. It helps you let go of some of the more irrational trails of thought that naturally come along with emotionally fuelled thoughts.

It does help to talk things through immensely. Not always, but a lot of the time it does.

1. How does cancer harm the body? What changes in cells allow cancer to develop?


Answers

Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and multiply (through a process called cell division) to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place.

Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue. Tumors can be cancerous or not cancerous (benign).

Cancerous tumors spread into, or invade, nearby tissues and can travel to distant places in the body to form new tumors (a process called metastasis). Cancerous tumors may also be called malignant tumors. Many cancers form solid tumors, but cancers of the blood, such as leukemias, generally do not.

Benign tumors do not spread into, or invade, nearby tissues. When removed, benign tumors usually don’t grow back, whereas cancerous tumors sometimes do. Benign tumors can sometimes be quite large, however. Some can cause serious symptoms or be life threatening, such as benign tumors in the brain.
