Endometrial hyperplasia

The process often arises in

Endometrial Carcinoma:

Carcinoma of the endometrium arises from the

A

uterine lining and is the most frequent cancer of the female genital tract in the Western world (due to decreased prevalence of cervical carcinoma secondary to PAP test).

70
Q

Endometrial Carcinoma

Most cases are diagnosed between the ages of

A

55-65 and are very uncommon prior to the age of 40.

71
Q

Endometrial Carcinoma

The cancer tends to arise in

A

two clinical settings, each associated with a specific type of endometrial carcinoma: perimenopausal women with evidence of estrogen excess (endometrioid carcinoma, more common type) and in older women with endometrial atrophy (serous carcinoma).

72
Q

Endometrial Carcinoma

The majority of these cancers appear to be associated with

A

increased estrogen stimulation with similar risk factors as endometrial hyperplasia.

73
Q

Endometrial Carcinoma

The most common early symptoms are

A

leukorrhea and irregular bleeding, a red flag in postmenopausal women.

74
Q

Endometrial Carcinoma

standard of care with the addition of antiestrogen chemotherapy for disseminated cases.

76

80
Q

Polycystic ovarian disease

It is generally diagnosed after

81
Q

Polycystic ovarian disease

The condition was named due to the presence of

A

A

miscellany of benign lesions. The discussion will be limited to the three most frequent abnormalities of the breast.

101
Q

BREAST DISORDERS

Fibrocystic changes apply to

A

breast alterations which arise as an exaggeration and distortion of the cyclic breast changes that occur normally in the menstrual cycle.

102
Q

BREAST DISORDERS

Fibrocystic changes consist of

A

overgrowths of the fibrous stroma, the epithelial elements or a proliferation of both.

103
Q

BREAST DISORDERS

A

reproductive life but may persist after menopause.

104
Q

BREAST DISORDERS

107
Q

BREAST DISORDERS

However, there is a slightly increased risk with

A

florid ductal hyperplasia; and if the hyperplasia is atypical, there is a significant increased risk.

108
Q

BREAST DISORDERS

Fibroadenoma is the most common

A

benign tumor of the female breast and usually appears in prepubertal girls and young women, with the peak prevalence in the third decade.

109
Q

BREAST DISORDERS

They result from increased

A

estrogen.

110
Q

BREAST DISORDERS

These tumors are

A

encapsulated and comprised of both glandular epithelium and fibrous tissue.

111
Q

BREAST DISORDERS

A

solitary, discrete, freely movable nodule (1-10 cm in diameter).

Carcinoma of the breast:

Carcinoma of the breast arises from the

114
Q

Carcinoma of the breast

Breast carcinoma was the number one cause of cancer deaths in women until

A

1986, when the increased prevalence of smoking caught up with females and lung cancer became number 1.

115
Q

Carcinoma of the breast

Of those women that develop breast cancer (253,00 US cases in 2017), approximately

A

one fourth will die of their disease.

116
Q

Carcinoma of the breast

It is the 2nd leading cause of

A

cancer related death in women (41,000 deaths in US for 2017).

117
Q

Carcinoma of the breast

Genetic factors, environmental influences (e.g. Exposure to ionizing radiation, diet, reproductive patterns, nursing habits, etc.) and hormonal influences (e.g. Prolonged exposure to exogenous estrogens) have been i

A

mplicated in the etiology.

118
Q

Carcinoma of the breast

About 10% of breast cancers are thought to be related to

A

specific inherited mutations.

119
Q

Carcinoma of the breast

In those cases related to specific inherited mutations (Majority seen with BRCA1, BRCA2 genes), the cancers appear in women under

A

40 years of age and more often are bilateral.

120
Q

Carcinoma of the breast

The lifetime risk of female breast cancer is

A

one in eight with 75% occurring in individuals over the age of 50

121
Q

Carcinoma of the breast

Early lesions are

A

freely movable, discrete, non-tender masses and most are found by self-examination.

122
Q

Carcinoma of the breast

Much less often, an occult lesion is detected by a

A

routine mammogram (Calcification or soft tissue density).

123
Q

Carcinoma of the breast

Most are identified in the

A

upper outer quadrant but lower inner quadrant and central lesions have lowest 5 yr survival (tumors tend to be larger by the time of detection).

124
Q

Carcinoma of the breast

The tumor has a tendency to become adherent to the body wall with

A

fixation of the lesion.

125
Q

Carcinoma of the breast

Adherence to the overlying skin results in

A

retraction or dimpling of the nipple (often the first indication of a lesion).

126
Q

Carcinoma of the breast

Tumor blockage of the lymphatics can result in

A

thickened skin which resembles the surface of an orange (peau d’orange).

127
Q

Carcinoma of the breast can be classified as

A

ductal carcinoma (arising from ductal epithelium) or lobular carcinoma (arising from glandular acini).

128
Q

Carcinoma of the breast

Both have noninvasive precursor stages, termed ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS), in which the

A

neoplasm has not penetrated the basement membrane and thus has not invaded or infiltrated the connective tissue stroma.

129
Q

Carcinoma of the breast

Current therapeutic approaches include combinations of

A

simple mastectomy or segmental resection of the mass (lumpectomy) with or without lymph node dissection, postoperative irradiation and/or chemotherapy.

130
Q

Carcinoma of the breast

The prognosis is

A

variable and dependent on several factors, including tumor stage.

131
Q

Carcinoma of the breast

While metastases may occur many years after apparent therapeutic control of the primary lesion, the prognosis
