Cancer can be treated by surgery, chemotherapy, radiation therapy, hormonal therapy, and targeted therapy (including immunotherapy such as monoclonal antibody therapy). The choice of therapy depends upon the location and grade of the tumor and the stage the disease, as well as the general state of the patient (performance status). A number of experimental cancer treatments are also under development.
Complete removal of the cancer without damage to the rest of the body (that is, achieving cure with near-zero adverse effects) is the ideal goal of treatment and is often the goal in practice. Sometimes this can be accomplished by surgery, but the propensity of cancers to invade adjacent tissue or to spread to distant sites by microscopic metastasis often limits its effectiveness; and chemotherapy and radiotherapy can have a negative effect on normal cells. Therefore, cure with nonnegligible adverse effects may be accepted as a practical goal in some cases; and besides curative intent, practical goals of therapy can also include (1) suppressing the cancer to a subclinical state and maintaining that state for years of good quality of life (that is, treating the cancer as a chronic disease), and (2) palliative care without curative intent (for advanced-stage metastatic cancers).
Yeah, into the mists of time and space
Where we have no say, over date and place, oh yeah
Don't get embarrassed if it happens a lot
That you don't know how you started
Or where you're gonna stop, oh, yeah
And if at times it seems insane, all the tears in searching
Turning all your joy to pain, in pursuit of learning
Buy a dream and hideaway, can't escape the sorrow
Your mojo will have no effect, as we head into tomorrow
Round and round like a twisted wheel
Spinning in attempt to find the feel, the feel
Find the path that will help us find
A feeling of control over lives and minds, oh, yeah
Yeah, yeah, yeah
And if at times it seems insane, all the tears in searching
Turning all your joy to pain, in pursuit of learning
Buy a dream and hideaway, can't escape the sorrow
Your mojo will have no effect, as we head into tomorrow
Yeah, yeah, yeah
And if at times it seems insane, all the tears in searching
Turning all your joy to pain, in pursuit of learning
Pray and act it will connect, can't escape the sorrow
Your mojo will have no effect, as we head
Into the stars and always up
Drinking from a broken cup
Whose golden gleam is fading fast
Praying that it has not passed
Oh, into tomorrow, oh yeah
Into tomorrow, oh, yeah
Oh, into tomorrow, ohh
Into tomorrow, ohh
Into tomorrow, ohh
Into tomorrow, ohh
