Questions and Answers

What is the process called when damaged or unneeded cells die in an orderly manner?

Mitotic death
Apoptosis (correct)
Necrosis
Cell division

How do hormone therapies primarily work in treating cancers that depend on hormones for growth?

By preventing the synthesis or action of specific hormones (correct)
By stimulating hormone production
By directly killing cancer cells
By making cancer cells more aggressive

What type of cancer cells can be affected by targeted therapies that induce apoptosis?

All types of cancer cells indiscriminately
Cells that follow orderly dying processes
Cells that avoid the normal dying process (correct)
Only those that grow in the absence of hormones

Flashcards

Apoptosis

A natural process where cells self-destruct when damaged or no longer needed.

Cancer cells and Apoptosis

Cancer cells often avoid apoptosis, allowing them to survive and grow uncontrollably.

Targeted Therapy

A type of cancer treatment that targets specific processes in cancer cells, often inducing apoptosis.

Hormone Therapy

Some cancer therapies, such as hormone therapy, can block the production or action of hormones that fuels cancer growth.

How Hormone Therapy Works

Hormone therapy can be a targeted therapy that works by either preventing hormone production or blocking its effects.

Study Notes

Cell Death in Cancer

Normal cells die in an orderly manner when damaged or no longer needed.
Cancer cells avoid this programmed cell death (apoptosis).
Targeted therapies can induce apoptosis in cancer cells.

Hormone Therapies for Cancer

Some cancers (e.g., breast, prostate) need specific hormones to grow.
Hormone therapies target hormone production or action.
Some therapies prevent the body from producing specific hormones.
Others block hormones from interacting with cancer cells.
