EFFECTS OF CANCER
   Disruption of Function- can be due to obstruction or pressure
      Hematologic Alterations: can impair function of blood cells
      Hemorrhage: tumor erosion, bleeding, severe anemia
      Anorexia-Cachexia Syndrome: wasted appearance of client
Paraneoplastic Syndromes: ectopic sites with excess hormone production
      ↑ Parathyroid hormone→ hypercalcemia
      ↑ secretion of insulin→ hypoglycemia
      ↑ Antidiuretic hormone (ADH) → fluid retention, HTN & peripheral edema
↑ Adrenocorticotropic hormone (ACTH): cause excessive secretion of cortisone (ie: fluid
retention, ↑ glucose levels)
      Pain: major concern of clients and families associated with cancer
      Physical Stress: body tries to respond and destroy neoplasm
      Psychological Stress
ASSESSMENT
      Nursing History
             Health History – chief complaint and history of present illness (onset, course,
              duration, location, precipitating and alleviating factors)
      Cancer signs: CAUTION US!

Discussions:
      A person with colon cancer may have diarrhea or constipation, or he may notice that the
       stool has become smaller in diameter
      A person with bladder or kidney cancer may have urinary frequency and urgency
A – a sore that does not heal
Sores that:
      Don’t seem to be getting better over time
      Are getting bigger
      Getting more painful
      Are starting to bleed
Discussions:
      Because tumor causes impaired circulation and oxygenation in the area.
      Small, scaly patches on the skin that bleed or do not heal may be a sign of skin cancer
      A sore in the mouth that does not heal can indicate oral cancer
U – unusual bleeding or discharge
      Blood in the urine and stool
      Discharge from any parts of the body*
Discussions:
      Blood in the stool is often the first sign of colon cancer
      Similarly, blood in the urine is usually the first sign of bladder or kidney cancer
      Postmenopausal bleeding (bleeding after menopause) may be a sign of uterine cancer
T – thickening or lump in the breast or elsewhere
      Any lumps found in the breast when doing BSE
      Any lump in the scrotum when doing self-exam
      Other lumps found in the body
Discussions:
      Enlargement of the lymph nodes or glands (such as the thyroid gland) can be an early
       sign of cancer
      Breast and testicular cancers may also present as a lump
I – indigestion or difficulty in swallowing
      Feeling pressure in throat or chest which makes swallowing uncomfortable
      Feeling full without food or with a small amount of food
Discussions:
      Cancers of the digestive system, including those of the esophagus, stomach, and
       pancreas, may cause indigestion, heartburn, or difficulty swallowing
O – obvious change in wart or mole
Use the ABCD Rule:
A – asymmetry
B – Border
C – Color
D - Diameter
Discussions:
      A- are mole looks the same or different
      B- sharp or ragged
      C-colors seen in the mole
      D-is mole bigger than a pencil eraser
      Moles or other skin lesions that change in shape, size, or color should be reported
N – nagging cough or hoarseness
      Change in voice or hoarseness
      Cough that does not go away
      Sputum with blood
Discussions:
Cancers of the respiratory tract, including lung cancer and laryngeal cancer, may cause a cough
that does not go away or a hoarse (rough) voice
U – Unexplained anemia
      Kidney makes a hormone ERYTHROPOITEIN
      Which signals the bone marrow to produce RBC
      Cancer disrupt this process by slowing erythropoietin production
      With cancer, RBC wears out faster than normal and are not replaced as quickly as they
       are needed
      Cancer cause bleeding which results in blood loss
Discussions:
In EACH CASE, fewer RBC means there is less hgb to carry O2 throughout the body
S – Sudden weight loss
      Tumor use your blood and nutrients and release your waste product inside your body
      Sometimes tumor release chemicals that can increase the body’s metabolism which can
       lead to unexplained weight loss
Physical Assessment
      Inspection – skin and mucus membranes for lesions, bleeding, petechiae, and irritation
              Assess stools, urine, sputum, vomitus for acute or occult bleeding
              Scalp noting hair texture and hair loss
      Palpation

Cancer Detection and Diagnosis
Discussions:
      Detecting cancer early can affect the outcome of the disease for some cancers. When
       cancer is found, a doctor will determine what type it is and how fast it is growing.
      He or she will also determine whether cancer cells have invaded nearby healthy tissue or
       spread (metastasized) to other parts of the body.
      In some cases, finding cancer early may decrease a person’s risk of dying from the
       cancer. For this reason, improving our methods for early detection is currently a high
       priority for cancer researchers.
Early Cancer May Not Have Any Symptoms
Discussions:
      Some people visit the doctor only when they feel pain or when they notice changes like a
       lump in the breast or unusual bleeding or discharge. But don’t wait until then to be
       checked because early cancer may not have any symptoms.
      That is why screening for some cancers is important, particularly as you get older.
       Screening methods are designed to check for cancer in people with no symptoms.
Cervical Cancer Screening
                                          Discussions:
                                                 A screening technique called the Pap test (or
                                                  Pap smear) allows early detection of cancer of
                                                  the cervix, the narrow portion of the uterus that
                                                  extends down into the upper part of the vagina.
                                                 In this procedure, a doctor uses a small brush or
                                                  wooden scraper to remove a sample of cells
                                                  from the cervix and upper vagina. The cells are
                                                  placed on a slide and sent to a laboratory,
                                                  where a microscope is used to check for
                                                  abnormalities.
                                                 Since the 1930s, early detection using the Pap
                                                  test has helped lower the death rate from
                                                  cervical cancer more than 75 percent.

      Since the 1930s, early detection using the Pap test has helped lower the death rate from
       cervical cancer more than 75 percent.
      Should abnormalities be found, an additional test may be necessary. There are now 13
       high-risk types of human papillomaviruses (HPV) recognized as the major causes of
       cervical cancer.
      The U.S. Food and Drug Administration has approved an HPV test that can identify their
       presence in a tissue sample. This test can detect the viruses even before there are any
       conclusive visible changes to the cervical cells.
Breast Cancer Screening
Discussions:
      Breast cancer can sometimes be detected in its early stages using a mammogram, an X-
       ray of the breast.
      Mammography is most beneficial for women as they age and undergo menopause.
       Mammography is a screening tool that can detect the possible presence of an abnormal
       tissue mass.
      By itself, it is not accurate enough to provide definitive proof of either the presence or the
       absence of breast cancer. If a mammogram indicates the presence of an abnormality,
       further tests must be done to determine whether breast cancer actually is present.
Prostate and Ovarian Cancer Screening
Discussions:
      The U.S. Food and Drug Administration has approved the PSA test along with a digital
       rectal exam to help detect prostate cancer in men age 50 and older. Doctors often use the
       PSA test and DRE as prostate cancer screening tests; together, these tests can help
       doctors detect prostate cancer in men who have no symptoms of the disease.
      Most men with an elevated PSA test, though, turn out not to have cancer; only 25 to 30
       percent of men who have a biopsy due to elevated PSA levels actually have prostate
       cancer, so researchers are working hard to find new clues.
      Experts are trying to develop better blood tests that might alert people to malignancies
       while the cancers are still in their early stages. For example, several new blood tests for
       ovarian or prostate cancer are under development.
Colon Cancer Screening
Discussions:
      A procedure called a fecal occult blood test (FOBT) detects invisible amounts of blood in
       the feces, a possible sign of several disorders, including colon cancer.
      The test is painless and can be done at home or in the doctor’s office along with a rectal
       exam. With an application stick, a dab of a stool specimen is smeared on a chemically
         treated card, which is tested in a laboratory for evidence of blood. If blood is confirmed
         in the stool, more elaborate tests may be performed to find the source of the bleeding.
        Some other options include sigmoidoscopy and colonoscopy. The former exam uses a
         lighted instrument called a sigmoidoscope to find precancerous or cancerous growths in
         the rectum and lower colon. The latter exam uses a lighted instrument called a
         colonoscope to find precancerous or cancerous growths throughout the colon, including
         the upper part.
Biopsy
Discussions:
        To diagnose the presence of cancer, a doctor must look at a sample of the affected tissue
         under the microscope. Hence, when preliminary symptoms, Pap test, mammogram, PSA
         test, FOBT, or colonoscopy indicate the possible existence of cancer, a doctor must then
         perform a biopsy, which is the surgical removal of a small piece of tissue for
         microscopic examination. (For leukemias, a small blood sample serves the same
         purpose.)
        This microscopic examination will tell the doctor whether a tumor is actually present and,
         if so, whether it is malignant (i.e., cancer) or benign.
        In addition, microarrays may be used to determine which genes are turned on or off in the
         sample, or proteomic profiles may be collected for an analysis of protein activity. This
         information will help doctors to make a more accurate diagnosis and may even help to
         inform treatment planning.
Microscopic Appearance of Cancer Cells
Discussions:
Cancer tissue has a distinctive appearance under the microscope. Among the traits the doctor
looks for are a large number of irregularly shaped dividing cells, variation in nuclear size and
shape, variation in cell size and shape, loss of specialized cell features, loss of normal tissue
organization, and a poorly defined tumor boundary.
