What is the difference between local and systemic cancer treatment?
Some are "local" treatments like surgery and radiation therapy, which are used to treat a specific tumor or area of the body. Drug treatments (such as chemotherapy, immunotherapy, or targeted therapy) are often called "systemic" treatments because they can affect the entire body.
How is systemic therapy given?
These are drugs that can be taken by mouth or injected into a vein, muscle, or another part of the body. The way the chemotherapy is given depends on the type and stage of the cancer being treated. The drugs enter the bloodstream and can reach cancer cells throughout the body.

What are the newest cancer treatments?
Immunotherapy is a new form of cancer treatment that uses the immune system to attack cancer cells. Interventional radiology involves minimally invasive techniques using needles and catheters, and provides an alternative to surgery for some patients.
Can cancer be cured completely?
Treatment. There are no cures for any kinds of cancer, but there are treatments that may cure you. Many people are treated for cancer, live out the rest of their life, and die of other causes.

Examples include vaccines to human papillomavirus (HPV), which can prevent cervical and anal cancers (and possibly and head and neck and tonsil cancers) and vaccines to hepatitis B virus (HBV), which can prevent liver cancer .
What is an active immune system?
Active. Adoptive. Active immune therapy (mediated by active immunity) aims to provoke or amplify an anticancer immune response in a patient with cancer. This can be done, for example, using a cancer cell vaccine alone or combined with an adjuvant, which boosts the desired immune response.
What are some forms of adoptive immune therapy?
Other forms of adoptive immune therapy include lymphokines and cytokines such as interferons and interleukins. These forms are less widely used in cancer therapy.
What are some examples of targeted therapy?
An example of targeted therapy is the use of tyrosine kinase inhibitors (eg, imatinib, dasatinib, nilotinib) in chronic myeloid leukemia, a cancer caused by one mutation ( BCRABL1 ).
How many cycles of MRI and CT are needed for cancer?
Imaging (CT, MRI, PET) is frequently done after 2 to 3 cycles of therapy to evaluate response. Therapy continues in responders or patients with stable disease. In patients whose cancer progresses, the regimen is often changed or stopped.
Do cytotoxic drugs kill cancer cells?
Cytotoxic drugs damage DNA and kill many normal cells as well as cancer cells. Antimetabolites such as fluorouracil and methotrexate are cell cycle–specific and have no linear dose-response relationship. In contrast, other drugs (eg, DNA cross-linkers, also known as alkylating agents) have a linear dose-response relationship, killing more cancer cells at higher doses. At high doses, DNA cross-linkers damage the bone marrow.
What is the best treatment for cancer?
to cure the cancer / cause long-term remediation. palliative therapy / reduction in severity of symptoms. neoadjuvant therapy before surgery / induction therapy before radiation. adjuvant therapy after primary treatment. to extend the survival time of the patient.
What is systemic treatment?

Either the body’s immune system or medical intervention prevents them from spreading broadly. Experts estimate 50% of discovered (diagnosed) cancers spread so far they are considered metastatic. Surgery and radiation are impractical for addressing distributed cancer.
Which is more appropriate for treating cancer?
Systemic therapy , which includes most methods of administering chemotherapy, works throughout the body, and is thus more appropriate for treating widespread cancer. The chemotherapy agent travels through the bloodstream (or perhaps the lymphatic system) to all areas of the body.

Why is chemo used for neck cancer?
In the past, chemotherapy for head and neck cancers was most commonly used for palliation (relief) of symptoms in cancers that recurred after other treatment methods failed and/or to slow the progression of cancer, rather than with the intent to cure the cancer.
Why is chemotherapy given in multiple doses?
Chemotherapy is usually delivered in multiple doses over defined periods of time and with recovery periods in between; this is because each administration of chemotherapy kills a certain percentage (or fraction) of cancer cells. By giving more doses of chemotherapy, more of the cancer cells are destroyed.
What is the goal of chemotherapy?
The goal is to shrink the tumor and/or see the response of the tumor to the chemotherapy and then to complete the treatment.
